Nonequilibrium Corner Expansion Flow of Moist Air,

Abstract

An experimental investigation of the nonequilibrium expansion flow of moist air around a sharp corner is reported. Heat addition within the expansion fan is accomplished by condensation by homogeneous nucleation of water vapor. Density measurements, obtained from flow interferograms, indicate that the flow field within the condensation zone depends on both expansion angle and radial distance from the corner. Measurements of the location of onset show that the leading edge of the condensation zone is concave with respect to the oncoming flow. An empirical relation between experimentally determined adiabatic supercooling and expansion cooling rate is obtained. (Author)
