摘要 对液环泵壳体型线进行优化分析,提出了基于直接自由曲面变形(DFFD)方法的液环泵壳体型线的响应面优化方法.采用DFFD方法对液环泵壳体型线进行精确的参数化控制,在控制变量空间进行了试验设计,采用VOF模型对液环泵内的气液两相流动进行数值模拟,对液环泵壳体型线进行响应面优化分析,建立了液环泵壳体型线与其进口真空度及效率之间的响应关系,实现了对液环泵进口真空度及效率的优化.算例优化结果表明:壳体型线对液环泵水力性能有较大的影响,在一定范围内可实现泵效率及进口真空度的提高;具有较大吸气区面积扩散比的壳体型线所对应的液环泵具有较高的进口真空度,而泵的效率随该面积比的变化规律正好相反;在试验设计变量空间,泵的效率随其进口真空度的增大近似呈线性下降趋势.

Abstract: To optimize the liquid-ring pump case, the response surface method based on the direct free-form deformation(DFFD)was proposed. The case profile of liquid-ring pump was parameterized precisely using the direct free-form deformation method. The design of experiment was carried out in the control variables space. The gas-liquid flow in the liquid-ring pump was simulated by using VOF multiphase model. The optimization analysis of the pump case profile was based on the response surface method, and the response relationship between the case profile of liquid-ring pump and the corresponding inlet vacuum pressure and efficiency was established. The inlet vacuum pressure and the pump efficiency of the liquid-ring pump were optimized respectively. The calculation case shows that the pump case profile has a great effect on the hydraulic performance of the liquid-ring pump. The pump efficiency and inlet vacuum pressure can be improved within a certain range. The pump case profile with a higher area expansion ratio for the suction zone would result in the higher inlet vacuum pressure, and the pump efficiency is on the contrary. With the increase of pump inlet vacuum, the pump efficiency shows an approximately linear decreasing in the design variable space.
