It is very difficult for the conventional numerical reservoir simulation theories to describe the characteristicoffluid flow in low permeability media, because they are all based on the Darcy's law.
而传统的油藏数值模拟理论都是建立在达西定律之上的，因而它很难反映低渗介质中的流体渗流特征。

The characteristic parameters offluid during the transition in boundary layer are obviously different from that of the laminar flow or the turbulent flow.
边界层转捩流动的特征参数明显不同于层流或湍流，转捩流动的这些特征直接影响着流体的动力、传热特性。

The Characteristicof two-phase fluid flashing flow in tube is analysed in this paper by means of numerical calculation.
