Flow Resistance of Metallic Screens in Liquid, Gaseous and Cryogenic Flow

Abstract

Fluid flow applications usually are connected with filtration issues. For chemical processes, engine fuel supply or in several other technical applications it is necessary to assure the pureness of the used fluid. In case of aggressive media, very high or very low temperatures, metallic woven screens are used. An important application for such screens is the filtration of propellant in space craft tanks and feed lines. In cryogenic propulsion systems the additional feature of the screens, to retain gas in a liquid flow, is used to ensure a bubble and gaseous free supply of propellant to the engine.
