Numerical Investigation of Non-Newtonian Casson Fluid Flow with Radiative Heat Transfer Over a Magnetized Stretching Surface.

A comprehensive study has been conducted on the numerical investigation of non-Newtonian Casson fluid flow with radiative heat transfer over a magnetized stretching surface. The study considers the influence of surface magnetization, thermal radiation, convection, and temperature fields. The study considers the influence of surface magnetization, thermal radiation, convection, and temperature fields. A novel modification to the Casson fluid model has been introduced by altering its order. Using a similarity approach, the governing equations are transformed into ordinary differential equations. The parameters governing the flow are analysed numerically. The effects of surface magnetization on the flow of this modified fluid are presented in tabular form. It is found that surface magnetization increases the thickness of the thermal boundary layer, thereby significantly enhancing heat transfer control. The magnetized surface also impacts skin friction, Nusselt number, and Sherwood number similarly. This study suggests the potential benefits of incorporating magnetized surfaces in fluid flow applications for efficient flow control, as well as the advantages of adjusting the Casson fluid order.
