【摘要】 膜技术广泛的应用于水处理过程中,而膜污染和浓差极化限制了它的推广应用。计算流体动力学的应用在减轻膜污染与浓差极化方面起到了非常显著的作用,论述了计算流体动力学技术在膜处理中强化传质、降低能耗方面的应用、膜组件几何形状的优化、描述膜处理过程中所应用的数学模型的发展以及有待进一步解决的主要问题。更多还原

【Abstract】 Membrane technology are now widely used in water treatment processes.However,membrane fouling and concentration polarization limit the application of membrane.Computational Fluid Dynamics(CFD) has been used as a powerful tool to reduce membrane fouling and concentration polarization.Mass transfer enhancement using CFD,energy consumption reduction,optimization of membrane geometry and development of mathematical model describing membrane treatment processes are concluded in this paper.更多还原
