现有的多孔介质多相流宏观运动方程在两个方面都不令人满意。一方面，不能预测特征实验特征，例如毛细管压力和饱和度之间的关系。另一方面，从众所周知的流体力学定律推导方程的理论尚未完成。在本文中，我们讨论了这些不足之处，并提出了一种替代的描述，这是基于能量平衡。我们
The existing macroscopic equations of motion for multiphase flow in porous media are unsatisfactory in two general respects. On the one hand characteristic experimental features, such as relationships between capillary pressure and saturations, cannot be predicted. On the other hand the theoretical derivation of the equations from the well-known laws of hydrodynamics has not yet been accomplished. In this paper we discuss these deficiencies and present an alternative description which is based on energy balances. Our
