Many studies on the propagation of the unsteady expansion wave in a pipe with area changes have been performed. However, there are a few studies on the interaction of the unsteady expansion wave with orifices in a pipe. This study is very important from a viewpoint of not only mechanical application but also for basic research in gasdynamics. In the present study, a computational fluid dynamics work was applied to clarify the effect of non-equilibrium condensation on compressible flows in an expansion tube with one or two orifices, and the time - dependent flow properties were discussed based upon the present computational results. As a result, it is clarified that the compressible flow around the orifice is strongly influenced by the non-equilibrium condensation.
