近年来，通过将旋流与超声速流中产生的凝析气的非平衡冷凝现象相结合，发展了一种凝析气分离提取技术。这种技术可以减小设备的尺寸，并且不使用化学品。本文利用湿空气在由内体和带旋流的外喷管组成的环形喷管内超声速流动中发生的非平衡凝结现象，对可凝气体分离的可能性以及喷管进口形状对流场的影响进行了数值研究。
Recently, by combining a swirl flow with non-equilibrium condensation phenomena of condensate gas generated in a supersonic flow, a separating and extracting techniques of condensate gas have been developed. This technique can reduce the size of the device and don’t use chemicals. In the present study, by using a non-equilibrium condensation phenomenon of moist air occurred in the supersonic flow in the annular nozzle composed of an inner body and an outer nozzle with a swirl, the possibility of separation of the condensable gas and the effect of shape of nozzle inlet on the flow field were examined numerically.
