A biofuel from any biodegradable formation process such as a food waste bio-digester plant is a mixture of several gases such as methane (CH4), carbon dioxide (CO2), hydrogen sulfide (H2S), ammonia (NH3) and impurities like water and dust particles. The results are reported of a parametric study of the process of separation of methane, which is the most important gas in the mixture and usable as a biofuel, from particles and H2S. A cyclone, which is a conventional, economic and simple device for gas-solid separation, is considered based on the modification of three Texas A&M cyclone designs (1D2D, 2D2D and 1D3D) by the inclusion of an air inlet tube. A parametric sizing is performed of the cyclone for biogas purification, accounting for the separation of hydrogen sulfide (H2S) and dust particles from the biofuel. The stochiometric oxidation of H2S to form elemental sulphur is considered a useful cyclone design criterion. The proposed design includes geometric parameters and several criteria for quantifying the performance of cyclone separators such as the Lapple Model for minimum particle diameter collected, collection efficiency and pressure drop. For biogas volumetric flow rates between 0 and 1 m/s and inlet flow velocities of 12 m/s, 15 m/s and 18 m/s for the 1D2D, 2D2D and 1D3D cyclones, respectively, it is observed that the 2D2D configuration is most economic in terms of sizing (total height and diameter of cyclone). The 1D2D configuration experiences the lowest pressure drop. A design algorithm coupled with a user-friendly graphics interface is developed on the MATLAB platform, providing a tool for sizing and designing suitable cyclones.

This paper develops a new tri-quadratic non-inverted skew upwind scheme (NISUS) for additional refinement of nodal integration points in numerical advection–diffusion of scalar transport. Using a control-volume-based finite element method, the performance of the eight-noded hexahedral formulation is compared with tri-quadratic hexahedral elements (27-noded hexahedral). As an extension of the NISUS formulation developed with eight-noded hexahedral elements, the new 27-noded hexahedral version uses isoparametric shape functions and integration point interpolation. The proposed method is applied to three cases of advection–diffusion of heat transfer and energy transport, including radial heat flow in a rotating hollow sphere, advection–diffusion in a cubical cavity, and combined advection/diffusion in an inlet/outlet tank. Performance improvement of the two versions of NISUS in terms of speed, accuracy, and stability are presented as a comparative assessment for the design of energy conversion systems.

The design of a preheating chamber for a safe flow of liquefied petroleum gas (LPG) or liquid fuel in a pressurized burner is investigated. In developing economies with an incessant scarcity of cooking gas, adulterated fuel is more a scarce commodity than a scary cause of fire accident to lives and household properties. Back-flow tendencies in conventional burners, associated with inevitable loss of pressure, mechanical wears, and seal leakages, are eliminated by the application of the concept of “sudden expansion,” while the fuel tends to flow back through the line at the downstream of the preheating chamber. Experimental setup of a novel feeding of liquid fuel from the overhead tank of the proposed design is compared with the performance of conventional burners. Pulsation due to back-flow tendencies of liquid fuel is calibrated for different heights (h) of burners, between the range of 46 mm and 60 mm. It is anticipated that the proposed design of burners will provide an effective flow of liquid fuel if uniquely characterized, using efficient treatment of the back-flow tendencies. Also, the proposed sudden expansion technology is capable of reducing the risk of an irritating exposure to adulterated fuel.

A conceptualized impeller called KIA is designed for impact agitation of food waste in a homogenizer. A comparative analysis of the performance of KIA is made with three conventional impeller types, Rushton, Anchor, and Pitched Blade. Solid–liquid mixing of a moisture-rich food waste is simulated under various operational speeds, in order to compare the dispersions and thermal distributions at homogenous slurry conditions. Using SolidWorks, the design of the impellers employs an Application Programming Interface (API) which acts as the canvas for creating a graphical user interface (GUI )for automation of its assembly. A parametric analysis of the homogenizer, at varying operational speeds, enables the estimation of the critical speed of the mixing shaft diameter and the deflection under numerous mixing conditions and impeller configurations. The numerical simulation of the moisture-rich food waste (approximated as a Newtonian carrot–orange soup) is performed with ANSYS CFX v.15.0. The velocity and temperature field distribution of the homogenizer for various impeller rotational speeds are analyzed. It is anticipated that the developed model will help in the selection of a suitable impeller for efficient mixing of food waste in the homogenizer.

An organic material is proposed as a sustainable sensitizer and a replacement for the synthetic sensitizer in a dye-sensitized solar cell technology. Using the liquid extract from the leaf of a plant called Mimosa pudica (M. pudica) as a sensitizer, the performance characteristics of the extract of M. pudica are investigated. The photo-anode of each of the solar cell sample is passivated with a self-assembly monolayer (SAM) from a set of four materials, including alumina, formic acid, gelatine, and oxidized starch. Three sets of five samples of an M. pudica–based solar cell are produced, with the fifth sample used as the control experiment. Each of the solar cell samples has an active area of 0.3848cm2. A two-dimensional finite volume method (FVM) is used to model the transport of ions within the monolayer of the solar cell. The performance of the experimentally fabricated solar cells compares qualitatively with the ones obtained from the literature and the simulated solar cells. The highest efficiency of 3% is obtained from the use of the extract as a sensitizer. It is anticipated that the comparison of the performance characteristics with further research on the concentration of M. pudica extract will enhance the development of a reliable and competitive organic solar cell. It is also recommended that further research should be carried out on the concentration of the extract and electrolyte used in this study for a possible improved performance of the cell.

An M.pudica-based organic solar cell model is developed for experimental investigation of UV light absorptivity within ethyl acetate and ethanol mixtures in order to predict charged ion mobility within a network of microchannels. A two-dimensional simulation of energy transport with a finite volume formulation is adopted, where the back field effect on the wafering technology and the optimisation of the energy conversion within the M.pudica-based organic solar cell can be investigated. A significant contribution of this study is the inclusion of the material characterisation of M.pudica as a potential source of energy supply. The developed model is proposed for performance improvement in the design of the organic solar cell. With a variety of imposed boundary conditions, the scalar transport variables and their responses to the environment are studied. The temperature specified on the faces with Dirichlet boundary condition is 100°C. The result of the surface temperature diffusion is presented. The temperature that diffuses into the cell layer ranges from 30°C to 77°C, suggesting a temperature range for manufacturing of the organic solar cell.

Thermal comfort modelling of a university cafeteria, represented by the space occupied by a manikin, is developed using a two-dimensional finite volume formulation. An energy audit assessment including performance data collected from both vendors and customers of the facility is performed. Environmental and physiological data are gathered and simulated using computational fluid dynamics (CFD) to obtain realistic solutions of the energy performance and thermal comfort, and the results are validated with thermal sensation models. The thermal sensation of the occupants within an asymmetrical environment like the 2001 campus cafeteria is validated with Fanger's model, using the temperature distribution predicted with CFD. A Newton-Raphson method permits optimisation of the insulation thickness, which is capable of altering the asymmetric variation of the indoor environment and the possible attainment of energy savings through optimal building materials.

Numerical simulations of boundary layers play a significant role in the study and interpretation of physical experiments for theoretical explanations of boundary layer disturbances. The influence of thermal boundary layer on the control of heat transport across flat plates is particularly examined. The Crank-Nicolson differential method, which is widely favoured for finite-difference modelling of boundary layer equations, is reviewed. The stability of this method is compared with other numerical approaches in order to establish the appropriate scheme for sustainable applications, involving the design of any conjugate system with heat transfer between the solid and fluid interface. Specific applications to the analysis of cabin comfort in automobiles are anticipated.

The electricity consumption patterns of food vendors within the University of Lagos 2001 Cafeteria complex on daily and seasonal bases as function of users' behavioral and load demands are characterized. This paper investigates the capability of using multivariable linear regression (MLR) and condition demand analysis (CDA) as methodologies to determine the consumption patterns of unmetered food vendors in a deregulated power system. These approaches can help in developing a unique sustainability model, based on food vendor's behaviour from the use of appliances in the cafeteria. It is anticipated that this model would enable automatic allocation of electricity consumption to unmetered food vendors. The profiles for individual food vendors, which contribute towards the aggregate load profile for the cafeteria complex, are characterized. The integration of this load-shape allocation model with the ongoing development of an alternative renewable power generation from food waste is capable of reducing peak-demand from the local grid.

Numerical simulation of a suspended stirrer within a homogenizing system is performed towards determining the mixing performance of a homogenizer. A two-dimensional finite volume formulation is developed for the cylindrical system that is used for the storage and stirring of biodegradable food waste from eatery centers. The numerical solver incorporates an analysis of the property distribution for viscous food waste in a storage tank, while coupling the impact of mixing on the slurry fluid. Partial differential equations, which describe the conservation of mass, momentum and energy, are applied. The simulation covers the mixing and heating cycles of the slurry. Using carrot-orange soup as the operating fluid (and its thermofluid properties) and assuming constant density and temperature-dependent viscosity, the velocity and temperature field distribution under the influence of the mixing source term are analyzed. A parametric assessment of the velocity and temperature fields is performed, and the results are expected to play a significant role in designing a homogenizer for biodegradable food waste.

Effective pre-treatment of food waste is important to ensure that subsequent treatment in a biogas plant works well. This paper describes a two-dimensional finite volume model for the design of a homogenizing system for bio-degradable food waste from eatery centers. The numerical solver incorporates the analysis of the property distribution for food waste slurry in a storage tank, while coupling the impact of mixing on the slurry fluid. The partial differential equations which describe the conservation of mass, momentum and energy are simulated. The simulation covered the mixing and heating cycles of the slurry. The slurry fluid was exposed to a pretreatment temperature of 600 C. With carrot-orange soup as the studied food waste, constant density and a temperature dependent viscosity are assumed. The predicted results for velocity, pressure and temperature distribution are discussed and a source term for mixing was proposed. This assessment of distribution of velocity and temperature is expected play a role in future studies and designs of a homogenizer for biodegradable food waste.

Energy demand-supply mechanism with the load shape for both residential and commercial buildings in the Province of Ontario and Nigeria is studied with demand side monitoring of energy consumption. Thermal and electrical loads are characterized by certain predictor variables, including the consumers’ behavioural pattern, power ratings of energy appliances and weather conditions. The proposed bottom-up approach is capable of providing low-volume electricity and natural gas consumers, in a fully deregulated energy market, with competitive energy saving advantage, based on corrective monitoring of independent users’ demand loads. Special application of the bottom-up model-based facility characterization of demands for thermal comfort and indoor air qualityin a developing energy sector like Nigeria enables the development of planning tool for the proposed integration of renewable power systems. The developed DSMonitorTM app is capable of deploying an effective smart grid technology tool towards an improved building energy demand-supply balance at the individual end-user level.

Parametric studies of the effects of slip irreversibility in concentrating solar power (CSP)-powered bio-digester assemblies are investigated. Complexities regarding the identification of the appropriate electro-kinetic phenomena for certain electrolyte phases are reviewed. The application of exergy analysis to the design of energy conversion devices, like solar thermal collectors, for the required heat of formation in a downdraft waste food bio-digester, is discussed. Thermal management in the silicon-based substrate of the energy system is analyzed. The rectangular-shaped micro-channels are simulated with a finite-volume, staggered coupling of the pressure-velocity fields. Entropy generation transport within the energy system is determined and coupled with the solution procedure. Consequently, the effects of channel size perturbation, Reynolds number, and pressure ratios on the thermal performance and exergy destruction are presented. A comparative analysis of the axial heat conduction for thermal management in energy conversion devices is proposed.
