Heterogeneous condensation and evaporation induced by an unsteady rarefaction wave and by the passage of a shock wave in a water-nitrogen mixture is studied. Time resolved measurements of modal droplet radius, droplets radius, droplet number density, pressure, and gas density are presented. Condensation on Cr2O3-particles of about 10 nm starts at a saturation ratio of 3.4. Typical droplet radii and droplet number densities are 1.5 µm and 1011 m-3. A shock wave with Mach number 1.36 causes full evaporation in 4 ms.
