Mass Transfer Characteristics of MHD Casson Fluid Flowpast Stretching/Shrinking Sheet

The paper analyzes steady laminar boundary layer flow of low-conductivity Casson fluid over a stretching/shrinking sheet subjected to a transverse magnetic field in the presence of suction/injection when the fluid far away from the surface is at rest. This flow problem is mathematically modelled and the non-Newtonian fluid under consideration obeys the rheological equation of state by the Casson model. A similarity transformation converts the governing nonlinear partial differential equations into nonlinear ordinary differential equations, which are solved analytically. Using the stream function and velocity components, these results are analyzed in dependence on the Casson fluid parameters, Chandrasekhar number, and mass transpiration parameters.
