Study of binary nucleation in a Ludwieg tube
Abstract
The nucleation of ethanol-water mixtures is investigated using Ludwieg tube flow in combination with a differential interferometer and high speed photographic diagnostics. Results for alcohol-rich mixtures are found to give excellent agreement with calculations employing binary nucleation theory, although for high water concentrations differences are observed between experiment and theory. These differences are attributed to the characteristic change of the surface tension at high water concentrations. The importance of the expansion rate is also discussed.
