【摘要】：膜分离作为21世纪最具前景的高新技术之一,已广泛应用于化工、环境、生物、医药、电子等领域.然而,能耗高、产量低和寿命短三大问题始终制约着膜组件的应用.寻求合适的方法研究膜组件非理想流动下的传递过程,可用于指导膜组件放大和性能提升.计算流体力学(CFD)作为继量纲分析法和模型法之后一种新兴的化学工程研究方法,已被广泛应用于膜分离领域.本文以膜单元为对象的过程强化研究和以组件为对象的设备放大研究两方面综述了膜分离CFD模拟的最新进展.前者归纳了中空纤维膜、卷式膜和平板膜CFD研究所采用的模型和处理方法;后者总结了中空纤维膜组件三维CFD模拟的简化策略.然后提出两类CFD研究应着重发展的方向.最后根据CFD和膜技术的发展路线,预测两者在未来的结合将更加紧密.
[Abstract]:Membrane separation, as one of the most promising new technologies in the 21st century, has been widely used in chemical, environmental, biological, pharmaceutical, electronic and other fields. The application of membrane assembly is always restricted by the problems of low yield and short life. Computational fluid dynamics (CFD) is a new chemical engineering research method after dimensional analysis and model method. It has been widely used in the field of membrane separation. In this paper, the recent progress of membrane separation CFD simulation is reviewed in terms of process enhancement of membrane unit and equipment amplification of module. The former summarizes hollow fiber membrane. The model and treatment method adopted by the CFD Institute of coil membrane and flat membrane; The latter summarizes the simplified strategy for 3D CFD simulation of hollow fiber membrane modules, and then puts forward the development direction of the two types of CFD research. Finally, according to the development route of CFD and membrane technology, it is predicted that the combination of the two technologies will be closer in the future.
