Abstract
The onset of condensation of an argon-steam mixture in the expansion fan in a shock tube driver is experimentally measured by a Mach-Zehnder interferometer. The effect of a high expansion rate is determined and compared to the classical Volmer theory and the new DillmannMeier theory. The expansion of steam from states above of the saturation curve to states under this curve is simulated by a finite-volume method. An adaptive computational mesh is used to suppress the dissipative properties of the numerical procedure. The numerical results show a strong influence of the two-temperature approach on the magnitude of the condensation rate. The influence of the value of the sticking and accommodation coefficients on heat and mass transfer on the droplets can also be studied in this way.
