The novel wire gauze structured packing, PACK‐860, was characterized by means of numerical methods. The main features of PACK‐860 such as height equivalent to a theoretical plate (HETP) and dry/wet pressure drop were evaluated. The flow structure in this packing was described by numerical simulation. To estimate the amount of HETP and dry/wet pressure drop, three‐dimensional computational fluid dynamics (3D CFD) modeling with the Eulerian‐Eulerian multiphase approach was applied. The average relative errors between the results obtained from CFD simulation and experimental findings for mass transfer efficiency and wet and dry pressure drop were assessed. Numerical observations were found to agree well with the empirical results, proving the reliability of CFD simulations for modeling separation processes.

大容量结构填料的计算流体动力学表征

通过数值方法对新型钢丝网状填料PACK-860进行了表征。评估了PACK‐860的主要特征，例如，等效于理论塔板的高度（HETP）和干/湿压降。通过数值模拟描述了该填料中的流动结构。估算HETP量和干/湿压降，采用欧拉-欧拉多相方法进行三维计算流体动力学（3D CFD）建模。评估了从CFD模拟获得的结果与传质效率以及干，湿压降的实验结果之间的平均相对误差。发现数值观察结果与经验结果吻合得很好，证明了CFD模拟对分离过程建模的可靠性。
