摘要

中空纤维陶瓷膜技术展示了从空气中进行高性能氧气分离的巨大潜力。为了实现实际应用，有必要将单个中空纤维膜升级为膜堆和膜组件。然而，实验方法非常耗时且成本高昂。数学建模是一种经济有效的技术，而且在评估不同的升级策略时非常灵活。在这项研究中，以概念验证中空纤维膜堆的实验结果为基础，开发并验证了基于计算流体动力学的多物理场膜堆模型。通过全面模拟，了解了膜堆在不同运行条件下的行为。此外，还对不同的设计策略进行了评估，以优化膜堆的性能。

CFD simulation and design of ceramic hollow fiber membrane stack for oxygen separation

Hollow fiber ceramic membrane technology demonstrates a great potential for high performance oxygen separation from air. Upscaling of single hollow fiber membrane for membrane stacks and modules is necessary toward practical applications. However, experimental methods are very time-consuming and highly cost. Mathematical modeling is a cost-effective technique and very flexible to evaluate different upscaling strategies. In this research, built upon the experimental results of a proof-of-concept hollow fiber membrane stack, a computational fluid dynamics-based Multiphysics stack model is developed and validated. Comprehensive simulations are conducted to understand the behaviors of stacks under different operating conditions. Different designs strategies are also evaluated toward optimizations of stack performance.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
