Phase change materials (PCM) occupy an important position in modern technologies. The use of PCMs in parts of a building structure is a new trend in energy efficient construction. In this study, a building block model with PCM inserts was considered. The influence of the position of the insert and the melting point of the material on the thermal performance of the block during unsteady heating and cooling is analyzed. A numerical model that describes the unsteady process of phase transitions taking into account natural convection, formulated in dimensionless temperature, stream function, vorticity is used. It is shown that, depending on the position of the phase change material, the temperature of the outer surface can vary within several degrees and on the inner surface within one degree. Moreover, it is demonstrated that at higher melting temperatures the material can give a positive result only during hot days. Namely, if the melting point of the material is close to the maximum ambient temperature or higher, then the effect will not be observed, since the material will not start to melt.

In this study, the energy transference of a hybrid Al2O3-Cu-H2O nanosuspension within a lid-driven heated square chamber is simulated. The domain is affected by a horizontal magnetic field. The vertical sidewalls are insulated and the horizontal borders of the chamber are held at different fixed temperatures. A fourth-order accuracy compact method is applied to work out the vorticity-stream function view of incompressible Oberbeck–Boussinesq equations. The method used is validated against previous numerical and experimental works and good agreement is shown. The flow patterns, Nusselt numbers, and velocity profiles are studied for different Richardson numbers, Hartmann numbers, and the solid volume fraction of hybrid nanoparticles. Flow field and heat convection are highly affected by the magnetic field and volume fraction of each type of nanoparticles in a hybrid nanofluid. The results show an improvement of heat transfer using nanoparticles. To achieve a higher heat transmission rate by using the hybrid nanofluid, flow parameters like Richardson number and Hartmann number should be considered.

This work reports the study of mixed convection of permeable fluid with Robin conditions in the vertical channel including the effects of chemical reactions. The fluid transport is designed by the Darcy-Forchheimer-Brinkman model. The series method is adopted for approximate solutions for governing equations considering the Brinkman number as the perturbation characteristic whose outcomes correspond to magnitudes of Brinkman number less than one. Adopting a numerical scheme followed by fourth order Runge–Kutta algorithm with shooting method, the solutions for bigger magnitudes of the Brinkman number are obtained. The present results for limiting cases are compared with the literature and good agreement is seen. For various values of thermal and mass Grashof numbers, porous parameter, inertial parameter, Darcy number and first order chemical reaction the problem is resolved for the same and distant Biot numbers reflecting the border temperatures symmetric and asymmetric. Finally, the outcomes are tabulated for wall friction parameters, Nusselt and Sherwood numbers for innovated parameters. It is noticed that enhancing buoyancy and dissipations, thermal Grashof number helps to improve the flow rate for all values of Biot number. The Schmidt and Soret parameters can improve concentration patterns. Nusselt number can be improved with thermal Grashof number and Brinkman number and it is dropped with inertia and porous parameters. The solutions have a very good agreement with Zanchini data without mass Grashof number.

The constant growth of urban agglomerations with the development of transport networks requires the optimal use of energy and new ways of storing it. Energy efficiency is becoming one of the main challenges of modern engineering. The use of phase change materials in construction expands the possibilities of accumulating and storing solar energy, as well as reducing energy consumption. In this study, we consider the problem of the effect of natural convection on heat transfer in a building block containing a phase change material. Heat transfer, taking into account melting in brick, was analyzed at various temperature differences. The mathematical model was formulated in the form of time-dependent equations of conjugate natural convection using non-dimensional stream function, vorticity, and temperature. The equations describing melting, taking into account natural convection, were solved using the finite difference method. Smoothing parameters were used to describe phase transitions in the material. As a result of calculations, local characteristics of heat and mass transfer at various points in time were obtained, as well as changes in temperature profiles on the side surfaces. It is shown that with a large volume of melt, natural convection increases heat loss by more than 10%.

Energy consumption for cooling and heating buildings should be reduced in the future to maintain suitable indoor thermal comfort at a lower cost. Numerical simulation of heat transfer within building systems can help to design the energy-efficient buildings. This article presents a fundamental theoretical research done to understand the effect of automation of the underfloor heating system in a room under the influence of ambient conditions on heat transfer. The considered physical process has been described mathematically taking into account the turbulent natural convection and thermal surface radiation within an air filled enclosure having a panoramic window. Sinusoidal boundary condition has been applied to the external surface of panoramic window to model the possible diurnal ambient temperature oscillation. An automation of the underfloor heating system is determined by the heater volumetric heat flux that magnitude depends on the ambient conditions. The governing equations with boundary conditions have been solved numerically by the finite-difference method. The influence of the relevant parameters, viz., surface emissivity, length of underfloor heating system and ambient boundary conditions has been investigated in detail. Distributions of integral and local characteristics illustrating flow and thermal structures in the large-scale enclosure have been studied. The contribution of the thermal radiative mechanism to the overall heat transfer is close in magnitude to the convective heat transfer even under normal room conditions.

Convective heat transfer under an influence of thermal radiation in a rotating chamber has been investigated numerically. The cavity has periodically heat-generating source, cooling vertical walls and heat-conducting bottom wall. Governing equations have been formulated using stream function, vorticity and temperature. The considered set of control equations has been worked out employing the finite difference procedures. Streamlines and isotherms for different angles of rotation have been shown and described in detail. The effects of emissivity, angular velocity and bottom wall thickness have been illustrated using the flow rate, average heater temperature, mean convective and radiative Nusselt numbers. The results demonstrate that lower wall thickness can significantly reduce the mean heater temperature.

Convective heat transfer is a major phenomenon in different technical and natural systems. This process can be found in enclosures under the different temperature distributions at bounded walls. In this research, the thermogravitation energy transport of a non-constant viscosity medium inside a 3D region under the non-uniform or uniform temperature profile at one of the vertical walls is addressed. The opposite border is at a low constant temperature, and the remaining borders are well insulated. The control equations with the border restrictions are reduced into a non-dimensional form and then integrated by the finite difference procedures. The control characteristics are the Rayleigh number and viscosity changeable magnitude. The impacts of these characteristics on the energy transference and flow structures are studied.

In this study, an analytical solution of a porous fin with natural convection and radiation heat transfer is carried out. For the first time, the analysis is accomplished in Local Thermal Non-Equilibrium (LTNE) model. The investigation is carried out on a porous fin with finite length and adiabatic tip. The Darcy model and Boussinesq approximation for buoyancy effects are used to evaluate the infiltration velocity in the porous medium. Two energy equations are solved using the Adomian Decomposition Method (ADM). The solution is validated with the numerical solution of the finite difference method, and with the asymptotic solution for the Local Thermal Equilibrium (LTE) model. The results are presented in terms of temperature profiles and total average Nusselt numbers. They pointed out the effects of internal and external radiation and convection heat transfer, as well as thermal conductivity ratio and dimensionless thickness. It was found that solid phase temperature profiles decrease as the Biot, Bi, and Rayleigh, Ra*, numbers decrease, whereas the difference between the solid phase and fluid phase temperatures, for assigned Bi, decreases for lower Ra. Thermal conductivity ratio and dimensionless thickness increase engender higher solid phase temperature for assigned Bi and Ra*. The total Nusselt number increases as Ra*, Bi and external radiation increase, whereas it decreases with the thermal conductivity ratio. Criteria to compare LTNE and LTE assumptions are proposed, and they highlight the fact that the minimum Biot number to accept the LTE assumption becomes lower as the Rayleigh number decreases.

In this paper, we present a comprehensive evaluation of low-rank fuel compositions obtained using multi-criteria decision-making methods. Here we used a unique combination of parameters, especially important for gaining an insight into the prospects of industrial combustion of water slurries based on waste. The research involved six sets of criteria (cost, energy efficiency, ease of preparation and storage, atomization, fragmentation, and emissions) including a total of seventeen characteristics determined experimentally. An integral efficiency indicator was calculated in each set using the Weighted Sum Model. After that, an overall indicator was calculated accounting for all the key factors. The integral indicator ranged from 0.4 to 0.9 in all the six categories of criteria. The lowest overall efficiency indicators (0.239–0.487) were typical of the fuel containing 50% of flame coal filter cake, 40% of water, and 10% of turbine oil. According to the analysis, the blends based on coal slime and water can be considered the best fuels. The main application of the research findings is the development of compositions to provide positive effects at the stages of fuel preparation, storage, transportation, atomization, and combustion.

Droplet interaction regimes in a gas depend on collision parameters and liquid properties. Such interactions may occur at various droplet and gas temperatures. A significant impact on droplet interaction may come from vaporization. It has been largely overlooked as a factor of switching between collision regimes (coalescence, bounce, separation, and disruption) and outcomes. We present the experimental research into the collision characteristics of water droplets heated up to the boiling temperature in a gas medium. The experiments are conducted with the main droplet parameters varied in the following ranges: 0.1–5 m/s velocities, 0.1–1 mm dimensions, and 0–90° impact angle. The videos of colliding heated droplets illustrate the formation of the interface within the coalesced droplet. A vapor zone is identified that is formed due to intense water evaporation from the surface of the two contacting droplets. The colliding droplets are found to localize a certain volume of vapor when the resulting interaction velocities are low and the collisions are head-on. The main characteristics of such vapor zones are established. The most valuable experimental findings are the vapor zone characteristics versus the Weber number, relative interaction velocity, and droplet size ratio, as well as the joint impact of the said factors.

The paper presents experimental research findings for the viscosity and stability of fuel slurries. Thirty compositions produced from coal sludge, lignite and bituminous coal were studied. Wood sawdust, used turbine oil, starch, neonol, xanthan and guar gums were used as additives. The viscosity of the fuel compositions varied from 106.89 to 2030.17 mPa∙s at a shear rate of 100 s−1. Adding up to 10% used oil or wood sawdust increased the slurry viscosity by 50–70% on average. When the shares of oil and biomass exceeded 5% and 10%, respectively, the slurry lost its fluidity. It was found that the mass fraction of the solid part in fuels based on coal sludge should be limited to ≈55%, if spraying or pipeline transportation is planned. A multifactor evaluation of the fuel mixture efficiency was performed using six different variations of distributing the significance (weight coefficient) of the factors under consideration. It was established that fuel mixtures based on coal sludge (i.e., coal processing waste) and water are the most preferable ones. It is shown that the viscosity of many fuel mixtures based on coal sludges corresponds to the conditions of industrial application of fuel slurries and liquids. The obtained findings may be applied when planning and optimizing the operating procedures at thermal power stations and boiler units intended for slurry fuel combustion. In particular, the results can improve the preparation, storage, transportation, and spraying of high-moisture fuel mixtures based on waste and low-rank materials.

This research presents experimental findings on the fragmentation of droplets of coal-water slurries containing petrochemicals heated on a substrate (300–600 °C), in an air flow (450–550 °C), and in a tubular muffle furnace (500–700 °C). The fuels were composed of water, coal, coal processing waste (filter cakes), used industrial turbine oil, sawdust, nut shells, and stabilizers (neonol, starch, and tween). Before ignition, heated droplets behaved in three possible ways: gradual shrinking due to moisture evaporation; significant surface deformation when subjected to heating and droplet breakup with large fragments separating from it; full breakup of a droplet into small fragments. We recorded the droplet breakup delay times and integral characteristics of secondary fragments (number, size, and surface area) in comparison with the same parameters of the initial droplet. We also established the impact of a set of factors (temperature, heating scheme, and component composition of droplets) on the above characteristics. Approximations were obtained for the dependences established to be used for mathematical modeling. Finally, the findings were compared with the earlier established characteristics of similar processes studied in experiments with emulsion droplets and two-component immiscible droplets containing liquid combustible and noncombustible components.

The heat transfer enhancement and fluid flow control in engineering systems can be achieved by addition of ferric oxide nanoparticles of small concentration under magnetic impact. To increase the technical system life cycle, the entropy generation minimization technique can be employed. The present research deals with numerical simulation of magnetohydrodynamic thermal convection and entropy production in a ferrofluid chamber under the impact of an internal vertical hot sheet. The formulated governing equations have been worked out by the in-house program based on the finite volume technique. Influence of the Hartmann number, Lorentz force tilted angle, nanoadditives concentration, dimensionless temperature difference, and non-uniform heating parameter on circulation structures, temperature patterns, and entropy production has been scrutinized. It has been revealed that a transition from the isothermal plate to the non-uniformly warmed sheet illustrates a rise of the average entropy generation rate, while the average Nusselt number can be decreased weakly. A diminution of the mean entropy production strength can be achieved by an optimal selection of the Lorentz force tilted angle.

The fluid flow over a yawed cylinder is useful in understanding practical significance for undersea applications, for example, managing transference and/or separation of the boundary layer above submerged blocks and in suppressing recirculating bubbles. The present analysis examines nonlinear mixed convection flow past a moving yawed cylinder with diffusion of liquid hydrogen. The coupled nonlinear control relations and the border restrictions pertinent to the present flow problem are nondimensionalized by using nonsimilar reduction. Further, implicit finite difference schemes and Quasilinearization methods are employed to solve the nondimensional governing equations. Impact of several nondimensional parameters of the analysis on the dimensionless velocity, temperature and species concentration patterns and also on Nusselt number, Sherwood number and friction parameter defined at the cylinder shell is analyzed through numerical results presented in various graphs. Velocity profiles can be enhanced, and the coefficients of friction at the surface can be reduced, for increasing values of velocity ratio parameters along chordwise as well as spanwise directions. Species concentration profile is reduced, while the Sherwood number is enhanced, for growth of the Schmidt number and yaw angles. Furthermore, for an increasing value of yaw angle, skin-friction coefficient in chordwise direction diminishes in opposing buoyancy flow case, whereas the results exhibit the opposite trend in assisting buoyancy flow case. Moreover, very importantly, for increasing magnitude of nonlinear convection characteristic, the liquid velocity and surface friction enhance in spanwise direction. Further, for increasing magnitude of combined convection characteristics, velocity profiles and coefficient of friction at the surface enhance in both spanwise and chordwise directions. Moreover, we have observed that there is no deviation for zero yaw angle in Nusselt number and Sherwood number.

The effect of triple diffusion on convection of viscous liquid in a vertical channel saturated with permeable material is explored subject to Robin conditions on the boundaries. Inside the duct, the salts of distinct compositions are diffused. Non-Darcy approach is used to describe the porous material influence on transport processes. Symmetric and asymmetric heating conditions are considered for the ambient temperatures close to the vertical channel borders. Heat is exchanged between the vertical plates and the external fluid. Initially, the solutions are found without an influence of viscous dissipation and buoyancy forces. Inclusion of these two effects leads to nonlinear equations and adopting Brinkman parameter as the perturbation characteristic for the solutions is procured. Owing to the limitation on the perturbation characteristic, the conservation relations are solved numerically using the Runge–Kutta procedure combined with shooting technique. The flow patterns are depicted for the properties of the heat and mass Grashof numbers, porous parameter, inertial parameter, Brinkman number, Biot numbers, and chemical reaction characteristics. The effects of these parameters are explored on the skin frictions and Nusselt numbers. In the case of dissipations caused by viscosity and Forchheimer drag term, the perturbation results and numerical solutions are equal for low magnitudes of perturbation characteristic.

The paper presents the experimental research findings on the collisions of droplets in a high-temperature gaseous medium. Solution droplets were studied colliding with each other and with water droplets. Significant differences were established between the conditions and characteristics of surface transformation and collisions between droplets of water and highly viscous solutions with low surface tension at different temperatures of the gaseous medium in the heating chamber. We determined how the temperature of the gas medium affects the position of droplet collision regime boundaries on the corresponding maps in the B(We) coordinates. We also established the main differences in the number and size of secondary droplets formed from the collision of two primary ones. Finally, key patterns were identified for the collisions between two-phase liquid droplets containing vapor bubbles at a high temperature of the medium.
