For assessing the risks of liquid hydrogen pump facilities, we conducted a test in which liquid hydrogen was pressurized to a maximum of 85 MPa and steadily released through a pinhole nozzle. In order to quantitatively evaluate the cooling effect ...
Space propulsion systems use screen mesh devices as filters to block contaminants and as propellant management devices to settle the propellants. The bubble point pressure indicates the basic capillary performance for liquid acquisition of screen ...
Heat transfer from inner side of a heated vertical pipe to liquid hydrogen flowing upward was measured at the pressures of 0.4, 0.7 and 1.1 MPa for wide ranges of flow rate and liquid temperature. Nine test heaters with different inner diameters o...
