    Samenvatting

    The traditional strongholds of the Shock Wave Research Center in Sendai, excellent experimentation, advanced numerical modelling, and being a most effective stimulus of international collaboration, have had a strong impact on the gas dynamics research program at TU/e.This is illustrated by means of recent results in the field of unsteady compressible flows with phase transition. The numerical program VAS2D of Sun and Takayama is combined with a theoretical model for droplet formation, growth, evaporation and disappearance. Numerical results are validated by a comparison with an interferometric recording of shock reflection from a double wedge, obtained at the SWRC. As a test experiment, the unsteady vortex shedding due to the passage of a strong expansion wave is studied in a Ludwieg tube.The test gas is dry or humid nitrogen.Iso-densit y contours are obtained with holographic interferometry. Effects of condensation and latent heat release are: reduction of pressure minima in the vortex and the appearance of condensation shocks and of shock vortex interaction.
