Heat and mass transfer in MHD stagnation‐point flow over a permeable stretching/shrinking sheet in the presence of radiation effect, soret effect and slip parameter

The numerical solution of steady two‐dimensional magneto hydrodynamic (MHD) stagnation‐point flow over a permeable stretching/shrinking sheet with radiation effect, Soret effect and slip parameter is considered in this study. The mathematical model formulation was done by reducing the governing partial differential equations to a system of ordinary differential equations by using a similarity transformation. Next, the ordinary differential equations were solved numerically using bvp4c functions and shooting method. Numerical results obtained are presented in tables and graphs, showing the effects of slip parameter and Soret effect on the flow field, heat and mass transfer characteristics. The dual solutions are found to existin a certain range of parameters, which is shrinking case, while the solution is unique for the stretching case. It is observed that as the slip parameter increases, the skin friction coefficient decreases while the Nusselt number and Sherwood number increases. It is observed that the Sherwood number decrease as the Soret effect increase. Results also indicate that slip effect widens the range of stretching/shrinking parameter for which solution exists.
