Flow separation zone

WebNov 1, 2024 · When the flow ratio is 1, the separation zone can be obviously seen, and the velocity (w) in the z-direction of the separation zone is significantly greater than that … WebAn adverse pressure gradient causes the separated flow, and where we see separated flow there is lower pressure. However, the separation of flow is not the instigator, it is the adverse pressure gradient in viscous fluids due to shear stress and the retarding forces acting on the fluid as it flows past a body that causes the flow separation.
