Abstract

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.
