Several materials, such as aluminum and copper, exhibit non-Newtonian rheological behaviors. Aluminum and copper nanoparticles are ideal for wiring power grids, including overhead power transmission lines and local power distribution lines, because they provide a better conductivity-to-weight ratio than bulk copper; they are also some of the most common materials used in electrical applications. Therefore, the current investigation inspected the flow characteristics of homogeneous–heterogeneous reactions in a hybrid nanofluid flowing over a rotating disc. The velocity slip condition was examined. The energy equation was developed by employing the first law of thermodynamics. Mixed convection thermal radiation and the convective condition effect were addressed. The dimensionless governing models were solved to give the best possible investigative solution using the fourth- and fifth-order Runge–Kutta–Felhberg numerical method. The effects of different influential variables on the velocity and temperature were scrutinized graphically. The effects of the variation of various sundry parameters on the friction factor and Nusselt numbers were also analyzed. The results revealed that the velocity gradient increased significantly for augmented values of the mixed convection parameter. Here, the velocity gradient increased more rapidly for a hybrid nanoliquid than for a nanofluid. The thermal distribution was enhanced due to a significantly increased radiation parameter.

In the present decade, research regarding solar thermal air heaters (SAHs) has noticed a continuous progression in thermo-hydraulic performance augmentation approaches. There now exists a wide variety of thermo-hydraulic performance augmentation approaches and researchers have designated various structures. Nevertheless, there seems to be no generalization to any of the approaches employed. The present numerical investigation reports on the thermo-hydraulic characteristics and thermal performance for flow through a varied length (full, medium, half, and short length) dimple solar air heater (SAH) tube. The study highlights recent developments on enhanced tubes to augment heat transfer in SAH. The influence of different length ratio, dimple height ratio (H), and pitch ratio (s) on thermo-hydraulic characteristics have been investigated in the Reynolds number (Re) range from 5000 to 25,000. Air is used as the working fluid. The commercial software ANSYS Fluent is used for simulation. The shear stress transport (SST) model is used as the turbulence model. Thermal energy transport coefficient is increased in the full-length dimple tube (FLDT), compared to the medium-length dimple tube (MLDT), half-length dimple tube (HLDT) and short-length dimple tube (SLDT). Similarly, the pitch ratio (s) has more influence on Nusselt number (Nu) compared to the dimple height ratio (H). The friction factor decreases with an increase in pitch ratio. Nu increases and f decreases with increasing Re for all combinations of H and s. Low s and higher H yields high enhancement of HT and PD. Integration of artificial roughness on the tube increases the values of Nu and f by 5.12 times and 77.23 times for H = 0.07, s = 1.0 at Re value of 5000 and 25,000, respectively, in regard to the plain tube. For all the tested cases, the thermo-hydraulic performances (η) are greater than unity.

Heat transfer augmentation is an important method being employed to manage the challenges of high energy density devices to improve efficiency and prevent total damage. This method is also important to save on energy cost and reduce the overall bulkiness of heat transfer (HT) equipment. Present numerical investigation reports thermohydraulic characteristics for flow through a triangular solar air heater tube fitted with angular cut and varied length twisted tape inserts. Influence of different length twisted tape, angular cut angle (θ), and twist ratio (Y) on thermohydraulic characteristics has been investigated for Reynolds number (Re) ranging from 10,000 to 50,000. Air (Prandtl number = 0.707) is used as the working fluid. The shear stress transport model is used as the turbulence model. Thermal energy transport coefficient is more in full-length twisted tape compared to short-length entry twisted tape and short-length middle twisted tape. Similarly, twist ratio (Y) has more influence on Nusselt number compared to the angular cut angle (θ). Friction factor decreases with increase in twist ratio. For all the tested cases, the thermohydraulic performance (η) are greater than unity. Exergy analysis is done and presented. The current study also reported statistical analysis of the heat and fluid flow by using an ANN approach. The machine learning model is assessed and found accuracy of 98.5% on unidentified data. Substantial data for HT and thermal performance are generated, which is very much advantageous for the designing a solar air heaters.

This study explores the effects of electro-magneto-hydrodynamics, Hall currents, and convective and slip boundary conditions on the peristaltic propulsion of nanofluids (considered as couple stress nanofluids) through porous symmetric microchannels. The phenomena of energy and mass transfer are considered under thermal radiation and heat source/sink. The governing equations are modeled and non-dimensionalized under appropriate dimensionless quantities. The resulting system is solved numerically with MATHEMATICA (with an in-built function, namely the Runge-Kutta scheme). Graphical results are presented for various fluid flow quantities, such as the velocity, the nanoparticle temperature, the nanoparticle concentration, the skin friction, the nanoparticle heat transfer coefficient, the nanoparticle concentration coefficient, and the trapping phenomena. The results indicate that the nanoparticle heat transfer coefficient is enhanced for the larger values of thermophoresis parameters. Furthermore, an intriguing phenomenon is observed in trapping: the trapped bolus is expanded with an increase in the Hartmann number. However, the bolus size decreases with the increasing values of both the Darcy number and the electroosmotic parameter.

A circular tube fitted with novel corrugated spring tape inserts has been investigated. Air was used as the working fluid. A thorough literature review has been done and this geometry has not been studied previously, neither experimentally nor theoretically. A novel experimental investigation of this enhanced geometry can, therefore, be treated as a new substantial contribution in the open literature. Three different spring ratio and depth ratio has been used in this study. Increase in thermal energy transport coefficient is noticed with increase in depth ratio. Corrugated spring tape shows promising results towards heat transfer enhancement. This geometry performs significantly better (60% to 75% increase in heat duty at constant pumping power and 20% to 31% reduction in pumping power at constant heat duty) than simple spring tape. This paper also presented a statistical analysis of the heat transfer and fluid flow by developing an artificial neural network (ANN)-based machine learning (ML) model. The model is evaluated to have an accuracy of 98.00% on unknown test data. These models will help the researchers working in heat transfer enhancement-based experiments to understand and predict the output. As a result, the time and cost of the experiments will reduce. The results of this investigation can be used in designing heat exchangers.

Herein, laminar convective heat transfer from two horizontally arranged spheres has been evaluated by using numerical models inside water-based fluids incorporated with alumina (Al2O3), copper oxide (CuO), and copper (Cu) nanoparticles. The problem was simulated for different Rayleigh numbers ranging from 103 to 106 and various volume fractions including 2, 4, 6, and 8%. The evaluation process included the perspective of both first and second thermodynamic laws. In-house FORTRAN code was provided to solve the equations based upon the finite volume method as well as the Multigrid acceleration. According to the obtained results, the average Nusselt number enhanced by 57.4% for both the spheres and plates with increment of the Rayleigh number from 103 to 106 for the constant volume fraction of 2%. In addition, nanoparticle type played a significant role on the heat transfer rate and generated entropy. Moreover, introduction of the Al2O3 nanoparticles into the water-based fluid resulted in approaching to the highest Bejan number of 0.98. Furthermore, the ecological coefficient of performance of CuO nanoparticles decreased by increment of the volume fraction at all Rayleigh numbers. In the volume fraction of 2%, it raised from 2.89 to 7.8 by increasing of the Rayleigh number from 103 to 106.

In this research paper, we examined a two-dimensional micropolar nanofluid flow in the light of a melting surface with warm nonlinear radiation and slip condition. Comparability transformations are utilized to deal with the problem equations for non-dimensionality. RKF 45-method is applied for the simulation of the demonstrated equations, and the biothermal framework is investigated for all the implanted parameters whose impacts are appeared through various graphs. Thus, fascinating outcomes exist in this paper because of the impacts of various constraints on various profiles.

Several parts of the Moringa oleifera plant have revealed incredible potential for water quality improvement. However, the purification potential of a combined leaf and seed extract of Moringa oleifera plants remains unexplored. To the best of our knowledge, this research would be the first to work towards exploiting the combined potential of a leaf and seed extract of the Moringa oleifera plant in the process of water purification. In this study, we investigated the combined effectiveness of the leaf and seed extract in the purification of groundwater. The jar test method was used to analyze the effectiveness of Moringa plant extract (in combination) on different quality parameters of groundwater. Treatment with the combined plant extract (seed and leaf) resulted in significant improvement of various physicochemical (hardness, pH, turbidity, Total Dissolved Solid (TDS), and metallic impurities) and biological parameters (E.coli count) over individual seed and leaf extracts in groundwater samples. Experimental findings have strongly shown the enhanced purification efficacy of the hexane extract of combined plant materials in comparison to the individual extracts, thereby providing us with a potent natural coagulant that could combat the side effects of chemical coagulants.

Three ultrafiltration membranes were prepared using phase separation techniques. The membranes were characterized by scan electron microscope, porosity, pore size distribution measurement, and mechanical properties. The membrane performance was carried out using synthetic solutions from humic acid and tap water to express the contaminated drinking water. The polyvinylidene difluoride (M2) has the highest tensile strength 33.2 MPa with elongation of 52.3%, while polyacrylonitrile (M3) has the lowest mechanical properties, tensile strength 16.4 MPa with elongation of 42.7%. Polyethersulfone membrane (M1) provides the highest removal of humic acid, which was 99.5, 98.8, and 98.2% using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively, while M3 provides the highest permeate flux which was 250, 234.4, and 201.4 l/m2 h using feed concentrations 0.1, 0.3, and 0.5 g/l, respectively. Analysis of water samples indicates that the prepared membranes can be used to treat the contaminated drinking water which produced the high quality of drinking water after treatment.

The present paper envisages on the electric resistance heating distribution on three-dimensional Carreau dissipated NF along a nonlinear stretching sheet. The characteristics of heat and mass transfer are conferred by utilizing nonlinear radiation and zero mass flux. The passive control on NPhas its own application in drug targeting therapy. Convectively hot fluid is placed near the stretching sheet. The governing Prandtl boundary layer equations are modeled using relative laws and transformed to highly nonlinear ordinary differential equations with similarity conversion variables. The dependent variables in governing equation are solved by shooting method with R-K scheme. A comparative study of Pseudoplastic and Dilatant fluids is deliberated in this study. Varied physical parameters, whose behaviors on the velocity, energy and species concentration are analyzed. Shear thickening fluid nature superiors the shear thinning fluid nature when the fluid flow swifts, whereas energy exchange from the system is more in Dilatant fluid. Heat transfer rate is higher when the fluid flow swifts. Heat transfer from the fluid to the surface is slow as the Eckert number along both x–y directions. The examination of present outcomes with the existing work has been made, which is good agreed. The present study reveals that the liquid stream velocity declines for the larger values of ratio of stretching rates parameter c and conflicting behavior is detected in tangential velocity.

The cooling capability of heat sinks is important for a central processing unit (CPU). In this work, simulation has been done to study heat transfer (HT) in a heat sink (HS) mounted on the triangular cylinder chip of a CPU is studied, to explore the thermofluid behaviour of the designed micro-pin-fin heat sink. Air cooling methods are used for heat extraction. This numerical work considers the effects of inlet turbulence intensity (TI) and fin diameter (D) of the micro-pin-fin on the performance of the heat sink. Turbulent SST model is applied to capture turbulence regime in the system. The heat transfer and pressure coefficient were obtained at different Reynolds number (Re) (i.e. different inlet velocities). As shown in this study, the Nusselt number (Nu) increases with increase in air flow velocity which enhance the heat extraction from CPU.

We present electronic and transport properties of a zigzag nanoribbon made of $\alpha-\mathcal{T}_3$ lattice. Our particular focus is on the effects of the continuous evolution of the edge modes ( from flat to dispersive) on the thermoelectric transport properties. Unlike the case of graphene nanoribbon, the zigzag nanoribbon of $\alpha-\mathcal{T}_3$ lattice can host a pair of dispersive (chiral) edge modes at the two valleys for specific width of the ribbon. Moreover, gap opening can also occur at the two valleys depending on the width. The slope of the chiral edge modes and the energy gap strongly depend on the relative strength of two kinds of hoping parameters present in the system. We compute corresponding transport coefficients such as conductance, thermopower, thermal conductance and the thermoelectric figure of merits by using the tight-binding Green function formalism, in order to explore the roles of the dispersive edge modes. It is found that the thermopower and thermoelectric figure of merits can be enhanced significantly by suitably controlling the edge modes. The figure of merits can be enhanced by thirty times under suitable parameter regime in comparison to the case of graphene. Finally, we reveal that the presence of line defect, close to the edge, can cause a significant impact on the edge modes as well as on electrical conductance and thermopower.

Entropy generation in a fully developed couple stress fluid flow through an inclined channel is the focus of the present article. The steady flow of the non-Newtonian fluid via the inclined channel is assumed to be heated isothermally at the boundaries. The formulation of both the fluid flow and heat are based on hydrodynamics and thermodynamics laws. Exact solutions are constructed the dimensionless governing equations. The accuracy of the two solutions are established by direct comparison with the limiting case previously obtained in the current literature. Solution profiles are also presented to demonstrate the effect of variations in the parameter values followed closely by extensive discussions.

To study the intricate natural convection in square cavity filled with porous medium with an electrically conductive fluid in the presence of internal heat source, a numerical methodology based on the finite volume method and a full multigrid acceleration is utilized in this paper. The Darcy–Brinkman is adopted to model the fluid flow and energy transport equations in order to predict the heat transfer process in the porous medium. Numerical solutions are generated for representative combinations of the controlling Grashof number (103 ≤ Gr ≤ 106), the Prandtl number (0.015 ≤ Pr ≤ 0.054), and the Darcy number (10−5 ≤ Da ≤ 10−2). Typical sets of streamlines, isotherms, and average Nusselt number profiles are presented to analyze the flow patterns set up by the competition between homogenous and porous medium. It is revealed that average Nusselt number values are strongly affected by the increase of Prandtl number and the presence of homogeneous medium overestimates the rate of heat transfer better than the presence of a porous medium.

The aim of this work is scrutinizing the consequences of non-linear radiation on MHD Casson nanofluid along thin needle. The situation has been mathematically modelled taking into account the thermo-diffuso and diffuso-thermo effects. Here two types of surfaces are dealt; one is fixed needle and other is moving needle. The Prandtl boundary layer equations are enclosed and solved numerically using similarity variables. Impact of different material parameters on the momentum, temperature and species concentration along with the quantities related engineering aspects like skin friction coefficient, rate of energy transfer and Sherwood number are obtained and illustrated through graphs. A comparison examination is made between studied Casson nanoflow usage makes the environment cool, reduces the friction at the surface. But Newtonian nanofluid is good for species diffusion. Numerical obtained solutions are contrasted with the published literature and found to be in nice agreement. The present exploration exhibits the prominent features in hybrid solar magneto-hydrodynamic nanofluid systems and aircraft technology.
