TS1-Engineering of Tank Measurement System

Abstract

As part of FLPP3 tests about the stratification with liquids in very low temperature regions must be made as validation for given computational simulation tools. Especially validation tests for the phenomena of sloshing, venting, filling and draining at different pressures levels are required. To perform these tests the DLR site Bremen has the infrastructure with a cryogenic laboratory to handle liquids at low temperature regions. As test fluid, liquid nitrogen (LN2) is used and given with a supply. Due to the requirements, gaseous nitrogen (GN2) and helium (GHe) are given to perform the pressure regions. As test vessel the cryogenic tank demonstrator (CTD) is used.
