Abstract: In this paper, we investigate the laminar two-dimensional boundary-laver flow of a dusty fluid over a wedge. The mainstream flow outside the boundary- layer is considered in the form of the power of distance along the wedge surface. It is also considered that the wedge is moving with velocity Uw opposite to the mainstream flows. The interest in boundary-layer flow over a wedge has gained considerable attention because of its wide range of application in various problems of atmospheric, engineering, physiological, industry and manufacturing process fields such applica- tions include polluting city air, motion of aerosols in the upper atmosphere, trans-port of suspended powdered materials through pipes, propulsion and combustion in rockets, continuous stretching of plastic films and flow of blood in arteries are some examples. Few examples of such technological process are the boundary layer along material handling convey ears and the boundary layer along a liquid film in condensation process. So the study of two dimensional boundary layer flow a wedge has gained much interest. The influence of dust particles on viscous flows has great importance in the petroleum industry and in the purification of crude oil. Other important in the boundary layer include soil erosion by natural winds and dust entrainment in a cloud during a nuclear explosion. This modelling results into the coupled partial differential equations which are transformed into ordinary differential equations using suitable similarity transformations. Numerical method based on Keller-box is used for the coupled system for various physical parameters such as non-Newtonian fluid index parameter m, pressure gradient β, mass concentration Parameter Mc and local fluid particle interaction parameter χ. The detailed hydrodynamics behind these effects is discussed.
