This study aims to analyze the thermal mechanism of mixed convection flow of Reiner-Philippoff nanofluid, with a focus on entropy generation. By modifying the thermal performances of nanomaterials and utilizing specific relations and similarity variables, the study explores the importance of entropy generation and heat and mass transfer phenomenon through numerical simulations and graphical analysis.
This motivating analysis aims to present the thermal mechanism for mixed convection flow of Reiner-Philippoff nanofluid with assessment of entropy generation. The thermal performances of nanomaterials have been modified by utilizing the nonuniform heat source/sink, Ohmic dissipations and thermal radiation consequences. The assumed surface is assumed to be porous with non-Darcian porous medium. The modified Cattaneo-Christov relations are followed to modify the mass and heat equations. The invoking of similarity variables results in differential equations in nonlinear and coupled form. A MATLAB-based shooting algorithm is employed to access the numerical simulations. The physical aspect of thermal model is graphically addressed for endorsed flow parameters. The importance of entropy generation is visualized with associated mathematical relations and physical explanations. The numerical values are obtained for the assessment of heat and mass transfer phenomenon.
