Vapor condensation behind a shock wave propagating through two-phase media with excessively large void fraction (vapor to liquid volume ratio) was investigated experimentally by using shock tube facility. A flow field of such media revealed itself largely different from that of pure gases in the process of attaining thermal equilibrium condition. In the former shock intensities P2/P1 realized are much weaker, and larger heat energy are transferred to the tube wall in the form of condensates. A series of investigations including schlieren photographs with the aid of high-speed drum camera illustrate a sequential change of generation, growth and evaporation of fluid condensates in the flow field. These imply that the phase change phenomenon caused by thermo-fluid dynamic behavior plays an important role in such flow field immediately after the shock. The relaxation time of the vapor flow behind a shock wave is in orders of magnitude longer than that predicted by one-dimensional analyses based on kinetic theory.
