Review of Research on Supercritical vs. Subcritical Fluids

A paper reviews theoretical and experimental research on the behaviors of supercritical fluids and, for comparison, subcritical fluids. Experiments with drops, isolated or in groups, streams, shear layers, mixing layers, jets, and sprays are tabulated and discussed as a precursor to forming a concept of fluid behavior. The physics of the supercritical and subcritical regimes is discussed, and major differences between observations in the two regimes are identified and explained.
