Due to open-cell foam materials have extensive application foreground in medium-low pressure drop reactors or reactive distillation with low liquid load operation, it has been a hot spot in this field to explore the liquid phase flow inside the pores of foam materials. The present investigation addresses the formation conditions of the vortex flow in matrix porous structure (MPS) that is made from 3D printing technology. An experimental system consisting of a high-speed camera with a macro lens and particle tracking system was used to investigate the effect of the liquid flow rate and the liquid viscosity on the vortex flow formation in MPS. The numerical analysis based on the CFD modeling was used to calculate the vortex flow behaviors and characteristics. This model is validated and compared with the results of experimental campaigns performed in MPS with the formation of stable vortex flow. It was also found that the radius and swirling velocity of the vortex can be decreased by increasing the liquid viscosity and it would be slightly affected by main flow velocity with 10 mL/min – 100 mL/min, which is helpful to construct the gas-liquid interface with the formation of vortex flow for realizing process intensification.

由于开孔泡沫材料在中低压降反应器或低液体负荷运行的反应蒸馏中具有广泛的应用前景，因此探索泡沫材料孔内的液相流动已成为该领域的热点。本研究解决了由3D打印技术制成的基质多孔结构（MPS）中涡流的形成条件。使用由带有微距镜头的高速相机和粒子跟踪系统组成的实验系统来研究液体流速和液体粘度对MPS中涡流形成的影响。基于CFD模型的数值分析被用于计算涡流行为和特征。验证了该模型，并将其与MPS中形成稳定涡流的实验活动的结果进行了比较。还发现通过增加液体粘度可以减小涡旋的半径和涡旋速度，并且主流流速为10 mL / min – 100 mL / min时，涡流的半径和旋流速度会受到轻微影响，这有助于构造气体-液体与涡流形成界面，以实现过程强化。
