完整而准确地模拟多孔介质中的两相流需要了解所有起相关作用的控制物理（和物理参数值），并了解每个物理对解决方案的影响。这里特别关注的是毛细管压力的影响和与之相关的长度尺度。本文的目的是提供指导，何时包括模型中的毛细管压力的影响，以及什么是所产生的长度尺度的限制，如果这些影响被包括在内。版权所有© 2011约翰威利父子有限公司.
A complete and accurate simulation of two‐phase flow in porous media requires knowledge of all the controlling physics (and values of physical parameters) that play a relevant role and an understanding of the effects of each one on the solution. Of particular concern here is the effect of capillary pressure and the length scale over which it is relevant. The goal of this paper is to provide guidance onto when to include the effects of capillary pressure in the model, and onto what are the resulting length scale restrictions if those effects are to be included.
