Magneto-hydraulic Casson fluid flow under the suction/blowing effects past over the porous stretching surface

Abstract

The purpose of this study is to provide the two-dimensional Magneto hydraulic Casson fluid under the suction/blowing effects of an unstable stretched surface past on the porous medium undertaken when a prescribed surface temperature (PST) occurs. The purpose of this study is to show the effects of the coupling heat and mass transfer in Casson fluid flow. In the system of heat and mass transfer, the action of the magnetic field is considered and PST presents the heat transfer analysis. Using the similarity transformations, the governing model based on the partial differential equations is turned into a set of ordinary differential systems. The mathematical computations have been performed through the bvp4c, i.e. inbuilt Matlab software. The numerical findings are graphically presented using the concentration, temperature, and velocity profiles for various model parameters. The local Nusselt, Sherwood and the skin friction coefficient have also been provided. The Local Nusselt number increases with the magnetic field and the porous media parameters, whereas the magnetic field parameter in combination with the porous media parameter retards the velocity profile. © 2022 Elsevier B.V., All rights reserved.
