In presence of thermal radiation through porous medium unsteady MHD Casson fluid flow past an accelerated vertical plate


Author(s): Dr. Anjan Kumar Deka

Abstract: In this chapter, an attempt has been made to investigate the boundary layer flow of on an unsteady MHD free convection heat and mass transfer flow of a viscous, incompressible and electrically conducting Cassonfluid past an infinite vertical plate embedded in a porous medium. Casson fluid model is used to characterize the fluid behaviour. Heat absorption parameter is incorporated into the equation for the temperature field. The magnetic Reynolds number is considered to be so small that the induced magnetic field can be neglected. Exact solution of the governing equations is obtained in closed form by Laplace transform technique. The expressions for fluid velocity, fluid temperature and species concentration are displayed graphically whereas the numerical values of skin friction, the Nusselt number and the Sherwood number are presented in tabular form for various values of pertinent flow parameters. It is found that the fluid velocity and skin friction are enhanced due to Casson parameters. The fluid velocity and fluid temperature are getting reduced due to heat absorption parameter. Heat absorption parameter has the tendency to reduce the skin friction at the plate. Furthermore, the surface shear stress increases with the increase in the Casson parameter.
