The shock tube can form a good plane wave, The cryogenic shock tube experiment has more phenomena than the room temperature shock tube experiment, evaporation and condensation will occur. The cryogenic experiment of shock tube is very important. Low temperature experiments verified the relationship between the condensing film and shock wave. With the development of aerospace technology, there is a lack of experimental devices for cryogenic shock wave. In this paper, a diaphragm less shock-absorbing tube with higher working efficiency is used. The low-pressure part of the diaphragm less shock tube is designed as a cryogenic device, and the low-temperature characteristics of the shock wave in the shock tube are studied. Finally, fluent is used to numerically simulate the shock wave flow state. more...
