Recently, by utilizing the non-equilibrium condensation phenomenon in the supersonic swirl flow, technology for the separation and extraction of condensable gases has been developed. However, there are many unresolved problems for performance of operating principle. In the present study, the effect of branch pipe on the non-equilibrium condensing flow with a swirl in a supersonic annular nozzle were investigated on the basis of the simulated results. As a result, swirling flow or expansion rate of branch pipe has strong effect upon condensate mass fraction at the nozzle exit.
