Book Description
A low-speed experimental investigation was made of the filling effect observed when a screen or similar resistance is placed across a diffuser. Results are given for three diffusers of circular cross section with a variety of screen arrangements. The filling effect was observed to be real in that screens could prevent separation or restore separated flow in diffusers even of extreme divergence and to depend on screen location and pressure-drop coefficient. The effects of single and multiple screens are shown and the mechanics of the filling effect and possible efficiencies are discussed, as well as applications to damping screens as used in wind tunnels to reduce turbulence.
