ABSTRACT
The present paper is devoted to describing the boundary layer flow of a non-Newtonian Casson fluid accompanied by heat and mass transfer towards a porous exponentially stretching sheet with velocity slip and thermal slip conditions in presence of thermal radiation, suction/blowing, viscous dissipation, heat source/sink and chemical reaction effects. The governing partial differential equations are reduced to a set of highly non-linear ordinary differential equations by using suitable similarity transformations and solved numerically by an implicit finite difference scheme known as the Keller box method. In the present work the effects of the non-dimensional governing parameters on velocity, temperature and concentration profiles have been discussed and presented graphically. As well as for the local skin-friction coefficient, Nusselt number and Sherwood numbers exhibited and examined. It is found that the temperature and concentration profiles are increasing to higher value when the Casson parameter increases but reverse is true for the velocity distribution. Finally, the velocity and temperature profiles are decreasing with the increasing values of the velocity slip and thermal slip parameters respectively.
