Transient multiphase multicomponent flow in porous media
A one-dimensional transient two-phase, two-component flow in a porous medium was investigated analytically. The flow is described by the use of a continuity equation for each component, a momentum equation for each phase, the first law of thermodynamics, state equations, and relations for the transport properties. Local thermodynamic equilibrium is assumed. The effects of condensation and evaporation are included. The analysis shows that the flow resulting from a step change in the state at the surface of a uniform semi- infinite porous medium may be described by a single variable, which is a simple function of position and time. Under other conditions, position and time must be separately specified to determine the state of the mixture. Results of calculations relevant to the flow of cavity gas following an underground nuclear explosion are given. (auth)
