A review on MHD flow and heat transfer of Casson fluid

Abstract

The present study examines the impact of the Lorentz force on the flow and heat transfer characteristics of a Casson fluid over a stretching sheet embedded in a non-Darcy porous medium, incorporating a slip boundary condition. The governing partial differential equations (PDEs) are transformed into ordinary differential equations (ODEs) using suitable similarity transformations and are subsequently solved numerically. The effects of key parameters including the magnetic parameter, porosity parameter, inertia parameter, and slip parameter on the velocity and temperature profiles, skin friction coefficient, and local Nusselt number are presented through tables. The results reveal that an increase in the slip parameter enhances the skin friction coefficient but reduces the heat transfer rate at the sheet surface. Furthermore, an increase in the Casson parameter elevates the fluid temperature while diminishing the velocity profile.
