Beschreibung:
(Abstract) In the frame WP3.4 of the PRESLHY project 10 experiments on LH2-pool formation above different substrates have been performed with the POOL-facility on a free field-test site located a few kilometers to the north of KIT Campus North. Substrates to be investigated comprised concrete, sand, water and gravel. Four of the experiments were made with artificial side wind of known direction and known velocity to investigate the influence of side wind on the formation and evaporation of the LH2-pools.

Substrates to be investigated comprised concrete, sand, water and gravel. Four of the experiments were made with artificial side wind of known direction and known velocity to investigate the influence of side wind on the formation and evaporation of the LH2-pools.
(Technical Remarks) The POOL-facility was controlled via a computer that was located in a tent in a distance of approx. 10 m behind the wall with the BOS-background pattern, but after the initiation of an experiment this computer was controlled remotely from a shelter in a distance of approx. 100 m to the facility The control computer was also used to display and save all sensor records (temperatures, H2-concentrations, ambient wind conditions) with a measuring frequency of 10 Hz via LabView. The POOL-facility itself mainly consists of a stainless-steel box (dimensions 0.5 x 0.5 x 0.2 m³) that is filled up to half the height (0.1 m) with different substrates that can be found in, or are feasible for various real LH2-applications. The substrates used in the tests were concrete, sand, water and gravel, with the concrete pool being prepared already more than 1 month prior to the first experiment to allow sufficient hardening and drying. Three boxes were fabricated for the experiments, so one of these boxes had to be used for the experiments with two substrates (water and gravel, gravel was kept in separate box when not used, so in all experiments with gravel the same stones were used as substrate). For thermal protection the outside of the boxes was insulated by Styrofoam plates on its ground face and the sides. Inside the substrate layer 8 thermocouples were positioned via holders prior to the filling of the box with the respective substrate. The substrate filled box was then positioned on a scale on a table and the super insulated hose from the LH2-trailer was then fixed to a rack on the top of the table that positioned its open end above the box.
