Second law analysis of MHD Casson and Maxwell fluid flow over a permeable stretching sheet with homogenous heterogeneous reactions and variable heat source

Abstract

Entropy generation analysis of MHD Casson and Maxwell fluid flow over a stretching sheet with space and temperature dependent non-uniform heat source/sink with porous media has been explored. Using appropriate similarity transformations, governing equations have been changed into ODE’s, and solved numerically using RK-fourth order method with shooting technique. The impact of pertinent parameters on velocity, temperature, entropy and Bejan number has been presented graphically. The skin friction and Nusselt number have been obtained and tabulated.
