Abstract

Supersaturated air exits whenever the amount of moisture present is larger than the amount that the air can carry at the prevailing air temperature. Applications involving supersaturated air include aircraft wing icing problems and industrial walk-in freezers operating at low temperatures. The ability to predict frost and ice formation patterns on cold surfaces in supersaturated air has historically been impeded by the lack of property data. The objective of this paper is thus to provide a methodology for deriving key properties of air under supersaturated conditions for the purpose of improving the prediction capability in situations involving simultaneous heat and mass transfer in supersaturated air.
