Abstract


The main aim of this paper is to theoretically investigate the steady two-dimensional electrical MHD stagnation point flow of Casson nanofluid over a non-linear stretching sheet. Problem formulation is developed in the presence of slip conditions and suction or blowing on the non-linear stretching sheet in a porous medium. The resulting governing equations are converted into a system of non-linear ODE’s by applying a suitable similarity transformation and then solved numerically by using a well-known Keller Box method. The effects of different physical parameters on the velocity, temperature and concentration profiles are shown and discussed. Numerical values of local Sherwood number and Nusselt number are tabulated.
