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

Kurzfassung

Fine metallic screens are important sub-systems in propellant tank systems of spacecrafts due to their application as filter devices. The flow resistance has to be known for a proper design of tank and feed line systems. In this paper the flow resistance of application-relevant metallic screens is investigated experimentally. The weave types “dutch twilled weave” (DTW) and “broad mesh” (BM) were studied. The description of BM geometry in literature is improper and a screen geometry model is developed, which is suitable for DTW and BM. The experimental data show good agreement with the literature.
