摘要

本文提出了一种宏观CFD方法来模拟工业过滤系统中的压降和流型演变，特别是塑料薄膜铸造中的聚合物熔体过滤。通过使用过滤器阻塞模型将过滤器渗透率与局部流体速度耦合，该方法避免了直接模拟颗粒输运，从而提高了计算效率。该模型已在复杂的真实过滤器几何结构中进行了验证，准确捕捉了压降趋势，并揭示了流动模式的演变和过滤器元件的阻塞情况。这种方法可以更有效地设计和分析工业过滤系统。

A CFD based approach to the modelling of pressure drop and flow pattern evolution through industrial filter systems

A macroscopic CFD approach has been developed to simulate pressure drop and flow pattern evolution in industrial filter systems, specifically for polymer melt filtration in plastic film casting. By coupling filter permeability to local fluid velocity using filter blocking models, the approach avoids direct simulation of particle transport, making it computationally efficient. The model has been validated against a complex real-world filter geometry, accurately capturing pressure drop trends and revealing how flow patterns evolve and filter elements block over time. This approach enables more efficient design and analysis of industrial filtration systems.

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
