As for the supersonic condensation on the cold wall related to the research of liquified air cycle engine (LACE), this study has been tried to clarify experimentally the non-equilibrium supersonic condensation on cryogenic wall by an original diaphragmless shock tube. A new driver section was developed, and together with the first version driver shock tube results, non-equilibrium condensation on cold wall cooled by liquid nitrogen has been investigated. Condensing liquid film thickness was measured by laser interferometric method behind the incident and reflected shock waves in ethanol vapor of room temperature and in R-134a in cold temperature range. Also the heat flux measurement by Pt thin film on glass wall was measured. The both results were compared and discussed. Simultaneously the flow visualization clarified the instability of the surface of condensing liquid film on cold wall. These results indicated the direction of the cryogenic supersonic condensation research on LACE.

对于与液化空气循环发动机（LACE）研究相关的冷壁上的超声速冷凝，本研究试图用原始无隔膜激波管对低温壁上的非平衡超声速冷凝进行实验澄清。研制了一种新的驱动装置，并结合第一代驱动激波管的结果，研究了液氮冷却冷壁上的非平衡冷凝现象。采用激光干涉法测量了室温乙醇蒸气和低温R-134a中入射激波和反射激波后的冷凝液膜厚度。并对玻璃壁上Pt薄膜的热流密度进行了测量。对两种结果进行了比较和讨论。同时，流动显示也阐明了冷壁上冷凝液膜表面的不稳定性。这些结果为低温超声速冷凝研究指明了方向。
