Heat and Mass transfer on 3D Radiative MHD Casson Fluid Flow over a Stretching Permeable Sheet with Chemical Reaction and Heat Source/Sink

Abstract

The objective of this research is to ascertain how 3D MHD heat transfer Casson fluid flow over a linearly porous stretched surface is affected by chemical reaction, radiation, and heat source/sink. The Roseland approximation is used to account for the radiation impact in the energy equation when examining the impacts of thermal radiation. Recently, there has been interest in heat transmission past a stretched sheet because of its numerous commercial applications and substantial impact on a variety of industrial processes.
These consist of metal spinning, plastic sheet extrusion, condensation, heat exchangers, MHD generators, and power plants. The governing equations and related boundary conditions are reduced to a dimensionless form using similarity variables, and the Runge-Kutta-Fehlberg method is then used to solve the problem. An increase in the Casson fluid parameter, magnetic field parameter
and Permeability parameter causes the velocity field to decrease in x and y directions and improve the temperature and concentration dispersion. Sherwood number and Skin friction coefficient over x and y direction are increasing function of Casson fluid parameter and Nusselt number is decreasing function while the reverse effect is seen in streatching sheet parameter. Nusselt number is increasing function of chemical reaction parameter, Schmidt number, Radiation parameter and heat heat source/sink parameters while the reverse effect is seen in Sherwood number.
