Numerical Study of Mixed Convective Heat Transfer Over a Moving Wedge with Slip Velocity Effects

Abstract

We study the combined effects of pressure gradient, the slip velocity and viscous dissipation on the laminar and mixed convective boundary layer flow associated with heat transfer over a moving wedge. Both mainstream flow and wedge velocity are taken to be as a power of distance along the wedge wall. The modeled boundary layer equations are reduced upon using the suitable similarity transformations to a set of ordinary differential equations. These governing equations are solved numerically using shooting method. The physical quantities such as the momentum velocity, temperature profiles, skin-friction coefficient and Nusselt number are determined and discussed. The numerical simulations show that both pressure gradient, slip velocity and Eckert number are significantly affect the boundary layer thickness, velocity and temperature profiles. These model parameters are evidently enhance the rate of heat transfer. Interesting physical mechanisms are discussed in detail.
