中心射流泵多参数优化设计

Multi-parameter optimization design of center jet pump

目前中心射流泵的优化设计,最多同时选取2个参数进行分析,由于影响性能的参数较多,很难得到最优结构。本文基于参数化建模,采用多参数优化设计方法,同时分析了面积比、喉嘴距、喉管长径比、渐缩段角度4个参数与中心射流泵性能的关系,得到了设计点下的最优结构。

At present, two parameters in optimization design of the center jet pump are simultaneously chosen at most. As there are many parameters which influence the performance, it is difficult to get the optimum structure. Based on the parameterized modeling, a multi-parameter optimization design is adopted, and at the same time, the relation of the center jet pump performance with area ratio, nozzle-to-throat spacing, length-diameter ratio of throat and angle of suction chamber is analyzed in this paper. The optimal structure at the design point was obtained.
