The source theory is applied to obtain approximate solutions for determining the time-dependent interfacial location and the rate of phase change at the interface of a suddenly pressurized, multicomponent liquid-vapor system. Numerical calculations for the phase change of one and two-component cryogenic systems of nitrogen-nitrogen, helium-nitrogen, and oxygen-nitrogen show that the approximate solutions which are of a considerably simpler form compare favorably with the existing exact solutions. A conclusion is reached that the approximation by the source theory is dependable for low rates of phase change. The applicability of the source theory is discussed in regard to the geometrical configuration of the system and the nature of the phase change.
