Numerical Investigation of Radiation and Magnetic Effects on Casson Fluid Flow Over a Porous Sheet in Presence of Constant Mass Flux

The present research article focuses on the impacts due to magnetic and radiation parameter on the steady 2D Casson fluid flow along a porous/permeable plate which is flat in nature. A uniform magnetic field of strength \(B_{0}\) is assumed to be applied normal to the sheet. It is assumed that the flow in the laminar boundary layer is two-dimensional. In this study, we have used similarity transformation by changing partial differential equations (PDEs) into ordinary differential equations (ODEs). ODEs are solved then using bvp4c package in MATLAB with a shooting approach. Physical quantities of engineering, science and industry interest, like Sherwood and Nusselt number, skin/surface friction are calculated for the prescribed fluid flow. Line graphs of concentration, velocity and temperature distribution are produced for abundant non-dimensional parameters included in the study. Later on, we have discussed outcomes of all parameters on the flow. Here, results show that velocity of Casson fluid reduces with rising magnetic parameter and grows with increasing radiation parameter. Temperature increases as both radiation and magnetic parameter increase. Magnetic parameter also enhances the Casson fluid’s concentration.
