Effect of Chemical Reaction on Heat and Mass transfer of Porous MHD Casson Nano Fluid with Melting and Joule heating

The purpose of this study is to use computational tools to evaluate the effects of Joule heating, chemical reactions and melting on heat and mass transfer of a non-Newtonian Casson nano fluid flow across a porous stretched surface. The governing equations containing partial derivatives are consistent with nonlinear ordinary differential equations. The transformations are subject to the similarity variable, which is employed in the equations' solution. To generate approximate answers, a numerical method based on the Shoot technique and the Runge-Kutta method is used. A graphic representation of the velocity, temperature, and concentration distributions is shown. Additionally defined for specific parameter values are skin friction, Nusselt number, and Sherwood number. According to the study's key findings, boosting the Joule heating parameter enhances the temperature profiles, increasing Magnetic and Permeability parameters decreases velocity but increases temperature. Porous material is found to have a considerable effect on the problem’s flow and thermal properties. When the current analysis findings are compared to the existing literature in specific settings, better agreement is observed.
