Diffusive-convective vapor transport across horizontal and inclined rectangular enclosures

Abstract The enhancement of vapor transport across horizontal and inclined rectangular (2D) enclosures by expansive convection is studied numerically for a range in Grashof number that extends up to boundary layer flow. Comparison is made with predictions of the simplifying model and resulting analytical treatment of Klosse and Ullersma for various aspect ratios of the enclosure. The influence of varying Schmidt and Prandtl numbers is investigated. Solutions for interfacial (growth) flux and temperature distributions are given, showing practically important non-uniformities.
