摘要
反渗透工艺在世界范围内广泛应用于海水淡化、废水处理和医药生产等领域。计算流体力学(CFD)的模拟能描述出多种流体的流动、传质和传热等相关物理过程,可以在反渗透膜组件的模拟中可视化流体流动情况和膜污染情况,对膜组件的设计与应用过程具有指导意义。文中综述了卷式反渗透膜组件中的流道隔网优化和膜污染过程的CFD模拟研究进展,以及一些特殊形式膜组件中CFD的应用可行性和成果,并提出了CFD模拟应用于优化反渗透膜性能可能的研究方向。
Reverse osmosis has been extensively applied in seawater desalination,wastewater treatment,and pharmaceutical production worldwide.CFD simulation can describe the flow,mass transfer,heat transfer and other related physical processes.It can visualize the fluid flow and membrane fouling in the membrane module,which has guiding significance for the optimal design and practical application of membrane module.In this paper,the CFD simulations of optimization of spacers and membrane fouling in spiral-wounded RO membrane module are reviewed.Feasibility and achievements of CFD in some special membrane modules are also introduced.Furthermore,the potential research directions of CFD simulation to optimize the performance of RO are proposed.
