چکیده
The focus of this study is to examine the effects of velocity-slip on the surface of the moving wedge on the laminar boundary layer flow of a viscous fluid, in addition to the heat transfer across the moving wedge. When fluid and solid interact, velocity-slip effects may have a major impact on most industrial applications. It is considered that the mainstream and wedge velocities and the shape of the velocity-slip depend on the distance along the boundary layer wall. These equations offer the essence of a set of ordinary differential equations for the momentum and thermal boundary layer systems. The numerical solutions reveal that when the velocity-slip and unstable parameters increase, the thermal and momentum boundary layers narrow. The momentum boundary layer domain also appears to be reduced due to pressure gradient effects. There is also little variation in the thermal boundary layers as the wall shear stress (skin friction) and temperature gradient curves grow flat with increasing velocity-slip parameter. The physical mechanisms underlying these remarkable results are further discussed.
