MHD and Cross-Diffusion Fluid Flow for Free Convection of Casson Fluid Due to A Stretching Cylinder

Abstract

The present communication is dedicated for understanding the control of Lorentz force, Soret, Dufour effect and body force on the convection-free flow of Casson fluid on heat and mass transfer due to a stretching cylinder. For the considered two-dimensional physical configuration, a non-linear partial differential equation which are coupled are derived as a governing equation to study the behaviour of concentration, temperature and velocity which in turn modified to differential equations which are ordinary and non-linear by employing a suitable similarity transformation. A well-known shooting technique is employed to understand the characteristic variations of the fluid flow with the influence of some of the non-dimensional parameters viz., Schmidt’s, Reynolds number, Soret and Dufour parameters, Hartmann number, Prandtl number. These parameters take a vital role in controlling fluid flow, heat and mass transfer in various real problem applications. The present results are contrast with the results of earlier study as a particular case and good agreement is found.
