MHD Casson Fluid Flow over an Infinite Vertical Plate with Suction/Injection and Viscous Dissipation.

Abstract

This study examines the magnetohydrodynamic (MHD) flow of a Casson fluid over an infinite vertical plate incorporating the combined effect of suction/injection, chemical reaction and viscous dissipation, thermal radiation. The governing nonlinear partial differential equations (PDEs) in dimensional form are transformed to non-dimensional form and finite difference method (EFDM) is used to numerically obtain approximations for the velocity, temperature and concentration of the fluid. Computations were performed to study the effect of key parameters embedded in the flow quantities. The results are shown graphically and discussed. It is observed that fluid velocity increases when thermal radiation, viscous dissipation, heat generation, Casson parameters, and Grashof numbers (thermal and mass) become stronger. Conversely, fluid velocity slows down as Prandtl numbers and magnetic parameters increase. Comparison of present results with the previous literature was carried out to show the accuracy of the results.
