Abstract

The effects of suction and injection on the steady boundary-layer flow of a non-Newtonian fluid, represented by a power-law model, over a moving permeable flat plate in a moving fluid are investigated. The governing equations are first transformed to a nonlinear ordinary differential equation, before being solved numerically. The effects of the governing parameters on the skin friction coefficient are analyzed and discussed. It is found that dual solutions exist when the plate and the fluid move in the opposite directions, near the region of separation. It is also found that the drag force is reduced for dilatant fluids compared to pseudo-plastic fluids. Moreover, the effect of suction is to increase the surface shear stress, while injection acts in the opposite manners.
