Within this document the test with the GPPS (Gas Port Phase Separator) under LH2 conditions is reported, where a mock-up model of the actual device will be used. While the actual GPPS-Device features a more complex design, the mock-up for the test consists of two parallel screens mounted inside annular container as illustrated in Figure 1. The purpose of the actual device is to separate the liquid and the gases phases at the outlet port, used for pressure relieve of the tank vessel, such that on most, which not all, circumstances no liquid can exit the tank vessel and only gas is blown off. This device uses a technique where a bubble is trapped between two meshes such that prevents any other liquid to enter the device. The operation and functioning of the GPPS (Gas Port Phase Separator) has been demonstrated with previous test setups has shown successful operation of similar devices with conventional storable test liquids under ambient temperature condition for various operation modes such as flow speed and pressure differences as well as LN2. The intention of the following test is to demonstrate the functioning of the device under the cryogenic temperature conditions of liquid hydrogen as a functional demonstration.
