Study on the gas retention capability of metallic screens

Kurzfassung

In tank systems of spacecraft’s and satellites, metallic screens are found to provide the possibility besides filtering to retain liquid and prevent gas breakthrough by capillary. For determining the maximum retention capability at screens, the so called bubble point, in this study experimental setups are developed to measure the bubble point pressure for metallic screens of type twilled dutch 165 x 1400, 200 x 1400 and 325 x 2300 with isopropyl alcohol, silicon oil and liquid nitrogen. The results are found to follow a linear fit within the investigated regime of fluid properties and are compared with literature values.
