Initial experimentation on the nonvented fill of a 0.14 cu m (5 cu ft) dewar with nitrogen and hydrogen
Abstract
A series of nonvented fills were performed on a 0.14 cu m (5 cu ft) stainless steel dewar. Fills were conducted with a 120 deg cone angle spray nozzle over a range of inflow and initial wall temperatures with both liquid nitrogen and liquid hydrogen. Fill levels in excess of 85 percent liquid were achieved for four out of four nitrogen and two out of five hydrogen tests. Previously developed analytical models were compared to the test results and shown to have general trend agreement.
