Analysis of mixed convective Casson fluid flow through vertical porous surface in presence of radiation

Abstract

The investigation explains the mixed convective Casson fluid flow behavior passed an exponentially stretching porous surface in the presence of radiation and chemical reaction under the influence of mixed convection. Perpendicular to the flow a uniform magnetic field Bo is applied. The controlling equations are mathematically turned into ordinary differential equations by implementing appropriate similarity transformations. The MATLAB built-in bvp4c approach is then used to solve the equations numerically. The results are graphically examined for a range of flow parameter values. Special attention is paid to how the mixed convection parameters (Gr/(Re^2) and Gc/(Re^2)) affect entropy production, as well as how the magnetic parameter (M) affects the temperature profile of the system. We have demonstrated that the mixed convection parameters and magnetic parameter have a positive impact on the entropy and temperature of the system, respectively. The increase of 200 % (approximately) in (Gr/(Re^2) and Gc/(Re^2)) there is an increment in the entropy by 113 % (approximately) and 84 % (approximately), respectively. Also, with the increase of 400 % (approximately) in magnetic parameter (M) there is an increase of 34 % (approximately) in the temperature profile.
