对膜组件内部流场进行了流体动力学数值模拟。膜表面被视为多孔壁。该模拟采用模块化设计，可支持许多可选功能，如湍流效应、压力相关边界条件和灵活的模块几何形状。扩散-对流方程被纳入一个简单的方式来模拟膜分离显示在现实的流行的流体动力学条件下的溶质浓度场。单组分流体动力学模拟的数值结果匹配现有的，但更繁琐的分析模型相当不错。
A numerical hydrodynamic simulation of the flow field inside a membrane module has been formulated and implemented. The membrane surface is treated as a porous wall. This simulation is modular in design and can support many optional features such as turbulent effects, pressure-related boundary conditions, and flexible module geometry. The diffusion-convection equation was incorporated in a straightforward manner to model a membrane separation showing the solute concentration field under realistic prevailing hydrodynamic conditions. The numerical results for one-component hydrodynamic simulations match existing but more cumbersome analytical models quite well.
