ESTIMATION OF MHD MIXED CONVECTION STAGNATION-POINT DOUBLE SLIP FLOW TOWARDS A VERTICALLY STRETCHING SHEET WITH VISCOUS DISSIPATION
This paper investigates the mixed convection stagnation-point slip flow of electrically magnetized fluid towards a vertically stretching surface. Viscous dissipation and double (hydrodynamic and thermal) slip are also considered. The self-similar ordinary differential equations are solved numerically. The effects of the governing parameters such as stretching parameter, the mixed convection, Hartman, Navier and thermal slip parameters and the Eckert number for both assisting and opposing flows are analysed. The variations in skin friction coefficient and Nusselt number with the governing parameters are expressed by correlation formulas. It was found that the skin friction coefficient is an increasing function of Hartman number only, whereas the Nusselt number was found to be an increasing function of the stretching parameter; for both assisting and opposing flows, respectively.
