Plane jets impinging on porous walls [PDF]

, 2002
The flow of a two-dimensional plane turbulent jet impinging on a porous screen has been studied experimentally. It is shown how the overall flow structure depends on the porosity of the surface. For low screen porosity (# < 0.41, say), transverse wall
