This paper presents accurate models evaluating the hydrodynamic and separation behavior of an innovative packing structure called Tetra Spline (TS) packing. The newly designed internal is a wire-based lattice packing fabricated via additive manufacturing for gas-liquid contact systems, such as distillation and absorption columns. Using dimensional analysis, four correlations are developed for the prediction of dry and wet pressure drops, flooding velocity, and HETP of the TS internals in a two-phase system, regardless of its physicochemical properties. The performances are modeled based on extensive experimental data described in a previous work. These data are obtained by performing hydrodynamic and mass transfer characterizations on fifteen different TS configurations. Then, some of the proposed correlations are compared to other models available in literature. The final step will highlight that after optimization of the geometrical parameters the TS packing can reach high performances.

本文介绍了评估称为Tetra Spline (TS)填料的创新填料结构的流体动力学和分离行为的准确模型。新设计的内部是通过增材制造为气液接触系统（例如蒸馏和吸收塔）制造的线基晶格填料。使用量纲分析，开发了四个相关性，用于预测两相系统中TS内部构件的干湿压降、溢流速度和 HETP ，而不管其物理化学性质如何。性能是基于先前工作中描述的大量实验数据建模的。这些数据是通过对 15 种不同TS进行流体动力学和传质表征获得的配置。然后，将一些建议的相关性与文献中可用的其他模型进行比较。最后一步将强调在优化几何参数后，TS填料可以达到高性能。
