MHD Radiative Casson Fluid Flow over a Non-linear Extending Surface with Cross-Diffusion Impact in the Presence of Buoyancy and Porous Impacts

Abstract

This research uses MHD Casson fluid flow with radiation, buoyancy, and joule heating impression over a non-linear extending surface. It also included the impressions of thermal diffusion—the Casson fluid’s flow characteristics in a transverse magnetic field. Partial differential equations change into an ordinary differential coupled system through appropriate similarity modification. Diagrams and tables are used to analyze the impacts of numerous non-dimensional parameters on velocity, temperature, and concentration with the help of the BVP4C technique and MATLAB software. The temperature and concentration profiles decline with increasing Dufour and Soret impressions, respectively. Velocity profile increases with increasing local thermal Grashof number while the reverse impression shows growing local concentration Grashof number. The skin friction rises with the local thermal Grashof parameter but falloff with the local concentration Grashof number. The Nusselt number increases with the Soret, Dufour, and radiation impacts. The skin friction coefficient, Nusselt number, and Sherwood number are also shown in the table with validation.
