DRAG ON AN MICROPOLAR FLOW PAST A SPHERE SPECIFYING UNIFORM VELOCITY AWAY FROM THE BOUNDARIES

A study of the effect of drag force on anmicropolar flow past a sphere specifying uniform velocity away from the boundaries. We find a similarity solution, assuming the fluid outside the sphere and satisfies the Eringen?s micro polar equations and applying no slip condition at the sphere of the surface. An appearance for drag force is obtained. It is found that the increase in the coupling parameter with fixed coupling stress parameter is to decreases drag. Further a reversed behavior is noticed that the drag is increases andthe same is represented graphically.
