In this study, an innovative wire gauze structured packing, namely PACK-1300XY with a specific surface area of 1300 m/m has been characterized by performing computational fluid dynamics (CFD) approach. Indeed, different features of this packing (height equivalent to a theoretical plate, wet/dry pressure drop, and mass transfer efficiency) were analyzed by analyzing the flow regime using the three-dimensional CFD approach with the Eulerian-Eulerian multiphase scenario. The results showed the mean relative deviation of 16% (for wet pressure drop), 14% (for dry pressure drop), and 17% (for mass transfer efficiency) between the CFD predictions and experimental measurements. These excellent levels of consistency between the numerical findings and experimental observations approve the usefulness of the CFD-based approach for reliable simulation of separation processes.
在这项研究中，通过计算流体动力学 (CFD) 方法对一种创新的金属丝栅结构化填料（即 PACK-1300XY）进行了表征，其比表面积为 1300m/m。实际上，通过使用三维 CFD 方法和欧拉-欧拉多相情景分析流型，对这种填料的不同特性（理论板当量高度、湿/干压降和传质效率）进行了分析。结果表明，CFD 预测值与实验测量值之间的平均相对偏差分别为 16%（湿压降）、14%（干压降）和 17%（传质效率）。数值结果与实验观测结果之间的这种优异一致性，证明了基于 CFD 的方法在可靠模拟分离过程方面的有效性。
