【摘要】 为研究了相间力对微孔通道内水-气两相渗流规律的影响,利用格子-Boltzmann方法建立了孔隙尺度下微孔通道内的水-气两相渗流驱替的数学模型。采用C++语言编制的程序对微孔通道内水-气两相渗流驱替过程进行了数值模拟。通过对模拟结果的分析发现:两相驱替的总体效果与相间力有较大关系,流固作用力越大,多孔骨架的亲水性越强,两相渗流的总体驱替效果就越好,驱替速度越大,反之亦然。更多还原

【Abstract】 To study the influence of interphase force on water-gas two-phase flow in microporous channels, a mathematical model of water-gas two-phase seepage in channel of pore-scale is established by lattice Boltzmann method. The process of water-gas two-phase seepage displacement in microporous channels is simulated by C++ program. it is found that overall displacement effect of two-phase flow is closely related to interphase force. The larger the fluid-solid force, the stronger the hydrophilicity of the porous skeleton, the better the overall displacement effect of the two-phase flow, and vice versa.更多还原
