A theoretical and comparative analysis of γAl2O3–H2O and γAl2O3–C2H6O2 nanoparticles with entropy generation and nonlinear radiation

Here nonlinear radiation influence in slip flow of viscous nanomaterial is modeled and elaborated. Rate of entropy generation is evaluated employing second thermodynamics relation. Energy equation is modeled via heat generation and thermal stratification aspects. Non-Darcy porous medium is considered. Prandtl number has an essential contribution in momentum and energy equations to control the boundary layer. For this purpose, effective and without effective Prandtl fluid models are utilized in forced convective nanomaterial flow over a stretched surface. Appropriate similarity transformations give the nonlinear systems. Influence of pertinent variables versus Bejan number and entropy rate are elaborated through graphs. Engineering quantities such as Nusselt number and coefficient of skin friction are examined graphically. The main conclusions are presented.
