Kinetic theory description and experimental results for vapor motion in arbitrary strong evaporation

The kinetics of the vapor motion due to arbitrary strong evaporation/condensation from an infinite, plane interphase boundary were studied using a moment method of the Mott-Smith, Liu-Lees type. Detailed calculations were performed for the case of net evaporation assuming a vapor of Maxwell molecules. An equivalence is shown to exist between the vapor motion and the gas flow effusing from a perforated wall. Simple transformation rules were established so that experimental information on evaporation can be obtained from measurements performed in effusive flow fields. The theoretical and experimental results are compared with existing analytical, numerical, and Monte Carlo results.
