T1 Length of Condensation Zone in Tubes with Supply of a Concurent Gas Jet into Nitrogen and Hydrogen Flows JF Heat Transfer Research JO HTR YR 2003 FD 2003-09-01 VO 34 IS 3&4 OP 11 AB The size of a nonequilibrium condensation region in a tube flow of cryogenic liquids (nitrogen, hydrogen) under subcooled conditions with axial supply of a gas jet in the direction of flow is investigated. Experiments were conducted in the visual test sections of the diameter of 95 and 140 mm which were made of quartz glass and were located in a low-pressure chamber. The axial input of gas flow was executed through a jet injector of the diameter of 6 and 8 mm. The experiments on the condensation zone length were generated using the representations about the predominance of turbulent splitting and condensation of steam bubbles. Generalizing relations for calculation of dimensionless lengths of the condensation zone in the flow of liquid nitrogen and hydrogen were obtained for the concurrent input of gas into the flow.
