摘　　要：采用非介入的表面反应气相传质实验来测定规整填料表面的传质系数分布,在此基础上建立了波纹规整填料的流动及传质CFD模型。采用该CFD模型与正交试验开发了一种新型填料,其通道的形状区别于传统波纹规整填料的三角形,采用具有更大水力半径的四边形。CFD模拟结果表明经过几何结构优化后的新型填料在保持良好传质性能的同时,压降减小22.22%~23.03%。A flow dynamics and mass transfer CFD model was established based on non-intrusive surface reaction gas mass transfer experiments which were carried out to measure the distribution of mass transfer coefficient on the surface of structured packings.A new type of packing was developed using the CFD model and orthogonal experiments.The channel shape of the new packing is modified from the traditional triangle to a quadrangle to increase the hydraulic radius.The CFD simulation results show that the new packing with optimized geometry can reduce the pressure drop by 22.22%~23.03%while maintaining good mass transfer performance.
