计算流体力学在反渗透膜分离中的应用

Application of computational fluid dynamics in reverse osmosis membrane separation process

综述了计算流体力学(CFD)在反渗透膜分离中的应用情况及研究成果。阐述了CFD技术由于精确、效率高、成本低、不受实验条件限制等优势而得到的广泛应用,为研究流体流动提供了新的手段。指出浓差极化和膜污染限制了反渗透技术的进一步广泛应用,而CFD技术则为研究该问题提供了一种强有力的工具。

Computational fluid dynamics （CFD） has been widely used with its unique advantage, and it offers a new method to study the fluid dynamics mechanism. Membrane fouling and concentration polarization have restricted further application of reverse osmosis. CFD is an effective tool to study membrane fouling and concentration polarization on membrane surface. The paper introduces the application of CFD in reverse osmosis membrane separation process and its research progress.
