Energy-separating properties of two-phase flow

A new, substantially nondissipative process of energy separation in two-phase flows has been investigated. Mixtures of air with water, kerosene, and an aqueous solution of diethylene glycol were studied at initial pressures of 3–20 bar. It was found that ice was formed in an air-water mixture issuing from a supersonic nozzle, and for a mixture of air with a nonfreezing diethylene-glycol solution the liquid obtained after nonequilibrium separation had a negative temperature. The possibility of effective freezing out of moisture on an uncooled solid surface exposed to a current of moist air from a supersonic nozzle was demonstrated.
