The test program for cryogenic hydrogen releases was split after initial discussions into a high pressure and a low pressure liquid hydrogen temperature part. This report deals with the high pressure releases at temperatures down to 80K only, so-called part A. However, because of certain adaptions the electrostatic build-up/ignition experiments planned for the last project phase could be addressed in combination with these experiments, i.e. considerably earlier.
This report contains the “meta data” of the respective experiments, providing detailed description of the experimental set-up, sensors, result data structure and access (sub-set of the result data is provided via KITopen). Detailed evaluation of the results, e.g. determining the discharge coefficient, as well as any modelling work is excluded here and left for subsequent work.
