基于物理学基本原理和能量守恒定律的精确检查,导出充满黏性流体多孔固体边界呈连续性要求的边界条件.当孔隙流体具有黏性时,多孔弹性固体就是一个耗散的充满黏性流体的多空固体.孔隙流体的黏性造成的耗散应力准确地表达了边界条件.边界上两种固体连接的不完全,导致孔隙流体的流出,多孔骨料两边微粒运动的不平衡.导出多孔-多孔固体界面孔隙局部连接时的数学模型.在该界面上,滑移的松-紧,以及孔隙开-合,能造成一部分应变能的耗散.数值结果表明,在水和饱和油砂岩之间的界面上,修正的边界条件将影响各向同性多孔介质中折射波的能量.
Based on the exact examination of the basic principles of physics and the law of conservation of energy, the boundary conditions for the continuity of the porous solid boundary filled with viscous fluid are derived. When the porous fluid is viscous, the porous elastic solid is a dissipative, viscous fluid Long and short solid. Dissipative stress caused by the viscosity of the pore fluid accurately expresses the boundary conditions. The incomplete connection of the two solids on the boundary leads to the outflow of the pore fluid and the imbalance of particle motion on both sides of the porous aggregate. A mathematical model for the local connection of pores in a porous solid interface where slip loose-tight and pore open-closed can cause dissipation of a portion of the strain energy.The numerical results show that between the water and saturated oil sands Interface, the modified boundary conditions will affect the energy of the refracted waves in isotropic porous media.
