节能型无堵塞纸浆泵的关键技术研究与产业化（系列报道之四）--基于CFD正交试验的纸浆泵叶轮优化

摘要

Through the orthogonal experiment and the numerical simulation, multi-blade impeller was optimized to get the optimal impeller parameters. For the long fiber with the bigger ratio of length to width, the design can raise effectively the carrying capacity of the impellers and reduce blockage.%借助正交试验法，通过CFD数值模拟，对多叶叶轮进行优化，获得最优的叶轮参数配置，Z=10， D2=350m m，b2=60m m，β2=45°，β1=60°。对于长径比较大的长纤维，该设计将能有效提高纸浆泵叶轮的通过能力，降低堵塞。
