MHD Boundary Layer Flow of Casson Fluid Over a Stretching/Shrinking Sheet Through Porous Medium

Abstract

MHD boundary layer flow of Casson fluid over a permeable stretching/shrinking sheet in a porous medium is investigated. Applying similarity transformations, the governing partial differential equation are converted into ordinary differential equation and solved it analytically. The effects of magnetic parameter, permeability parameter and Casson parameter on are presented graphically on velocity profiles while the local skin friction coefficient are presented through graphs. Our analysis reveals that the increase of Casson parameter the velocity is decrease and also reduce the boundary layer thickness.

Keywords: MHD, Casson parameter, permeability parameter, boundary layer, stretching/shrinking sheet.
