At present, the main methods for large-scale treatment of tritium-containing wastewater include electrolysis, catalytic exchange, low-temperature distillation, and water distillation. Among them, the water distillation method has the advantages of simple operation, non-corrosiveness, no hydrogen production, and no explosion, and has broad application prospects. Currently, the packing used in water distillation separation technology needs to be operated under low-pressure conditions. Studying the hydrodynamic properties of the packing under low-pressure conditions is crucial to the development and modification of the packing. In this study, the hydrodynamic properties of perforated triangular corrugated plate packings were explored based on CFD modeling and numerical simulation methods. SolidWorks software was used for modeling and fluent software was used for simulation, and the RNG k-ε model was selected as the turbulence model. To simulate the low-pressure environment of water distillation and more accurate
