Modification of Separating Flow.
Abstract
The usual physical description of separation is that an adverse pressure gradient causes the deceleration of the low momentum flow near the surface. The result is a reduction of hte velocity near the surface and a corresponding decrease in the shear at the wall as the slope of the velocity profile decreases. Finally, at some point, the shear stress at the wall vanishes and the flow separates. Downstream of this point the flow near the boundary reverses and a dividing streamline breaks away from the surface. Below this streamline the net flow is towards the separation point and above this streamline it is away from the separation point. This general type of flow field can generally be observed near the rear of bodies, in particular, flow separation occurs on the rearward part of bodies with a blunt shape.
