MHD Flow of a Casson Fluid over an Exponentially Inclined Permeable Stretching Surface with Thermal Radiation, Viscous Dissipation and Chemical Reaction

The present paper aims at investigating the steady two-dimensional MHD convective boundary layer flow of a Casson fluid over a permeable stretching surface in the presence of thermal radiation and chemical reaction. The stretching velocity, wall temperature and wall concentration are assumed to vary according to specific exponential form. Velocity slip, thermal slip, solutal slip, thermal radiation, chemical reaction and suction/blowing are taken into account. The non-linear partial differential equations of the governing flow are converted into a system of coupled non-linear ordinary differential equations by using the similarity transformations, which are then solved numerically by using bvp4c with MATLAB package. The expressions for velocity, temperature and concentration profiles are discussed graphically. With the aid of these, the expressions for the coefficient of skin friction, the rate of heat transfer in the form of Nusselt number and the rate of mass transfer in the form of Sherwood number are illustrated in tabular form.
