Abstract
The nucleation and condensation behind a partial liquefaction shock wave could influence the shock structure if the characteristic times for nucleation and change of state in the shock are of the same order of magnitude. To investigate this effect, thicknesses of partial liquefaction shock waves and shocks without condensation in perfluoro-n-hexane, obtained with the light reflectivity method, are compared. It could be shown that inside our parameter range, nucleation has no measurable influence on the thickness of the shock, in accordance with calculated nucleation rates. As a function of Mach number, shock thickness scales with the mean free path ahead of the shock also in case of condensation behind the shock. Droplet condensation behind the shock is monitored using light scattering and extinction. Calculated nucleation rates and droplet growth are in good agreement with our measurements.
