气液两相多组分非等温渗流的数学模型
Mathematical Model of Non-Isothermal Liquid-Gas Two-Phase Multi-Component Seepage Flow in Porous Media
摘要
Abstract
A set of mathematical model is developed for non-isothermal two-phase multi-com-ponent seepage flow by analyzing the interactions of gas and liquid in porous media.Special processes are considered in high temperature and high pressure environment,such as non-Darcy flow,water transition and heat radiation,the convection,dispersion,source,and sink terms.Moreover,a complete set of constitutive relations is proposed to close the governing equations,among which the formulas for calculating the specific internal energy and the spe-cific enthalpy are derived.Finally,this model is used to simulate the migration of explosive gas after underground detonation.The result suggests that,compared with the gas phase seepage model,this model can provide a more reasonable description for the gas transport in geological medium.关键词
