✦ Synopsis

This paper deals on molecular levels with the condensation parameter and the condensation coefficient (sticking probability) of both water and carbontetrachloride vapour. The time-dependent thickness of a liquid film on a shock-tube endwall behind a reflected shock wave is measured by an optical method based on multiple reflections of light in the film. The measured thickness of the film is compared with theoretical one which is a solution of gasdynamics equations under molecular gasdynamical boundary conditions. The condensation parameter and the condensation coefficient of the above two kinds of vapour are determined from the comparison between experiment and theory. They are reasonably explained by the transition state theory on the basis of statistical mechanics of gases and liquids.
