Gas-liquid two-phase flow analysis method

摘要

PPROBLEM TO BE SOLVED: To apply a homogenization method to a two-phase penetration flow in a porous structural body, achieve a theory construction for a multi-scale analysis, and provide its numerical analysis algorithm. PSOLUTION: In a vapor-liquid two-phase flow analysis method in which a flow of a vapor-liquid two-phase flowing in the porous structural body is analyzed by micro-macro scale, when a triaxial direction pressure gradient and water saturation are changed in a supposed cube micro structure, a vapor-phase penetration coefficient Ka, a liquid-phase permeation coefficient Kw, and a capillary pressure Pcaw are memorized as data, and by substituting a porous body shape of the porous structural body by an equivalent homogeneous body having the vapor-phase penetration coefficient Ka, the liquid-phase permeation coefficient Kw, and a capillary pressure Pcaw, the penetration flow analysis of a macro structure is carried out.
