To accelerate the design of separation columns, packing vendors seek a reliable model of the flow in the complex geometry of separation-column packing. We provide a computational-fluid-dynamics model for the gas flow through various types of structured packing consisting of corrugated sheets. The model is validated on experimental data measured on commercial structured packings Mellapak 250.X, 250.Y, 350.Y, and 500.Y. Furthermore, the measurements on Mellapak 250.X and 250.Y were performed with three different gases, He, N₂, and SF₆, to cover the widest possible range of operating conditions. A successfully validated model was used to estimate the dry-pressure loss in relation to the gas flow and selected geometric parameters of the packing. The modified geometric parameters were, specifically, (i) the slope of the packing channels to the horizontal plane, (ii) the specific area of the packing, and (iii) the packing-perforation density.

波纹板结构填料的气流的计算流体动力学分析：填料几何形状的影响

为了加快分离塔的设计，填料供应商寻求在分离塔填料复杂几何形状中可靠的流动模型。我们为通过各种类型的由波纹板构成的规整填料的气流提供了一种计算流体动力学模型。该模型已根据在商用规整填料Mellapak 250.X，250.Y，350.Y和500.Y上测得的实验数据进行了验证。此外，在Mellapak 250.X和250.Y上的测量是使用三种不同的气体He，N ₂和SF _6进行的，以涵盖最大范围的工作条件。一个成功验证的模型用于估计与气流和填料的选定几何参数有关的干压损失。修改后的几何参数具体是（i）填料通道相对于水平面的斜率，（ii）填料的比表面积，以及（iii）填料的穿孔密度。
