混输泵半螺旋型吸入室流场的三维模拟分析

Three-dimensional Simulation and Analysis of the Half-helix Suction Chamber for Multiphase Pump

吸入室的形状决定了混输泵的压缩级进口的速度分布,对混输泵的性能有一定的影响。利用先进的三维模拟计算软件STAR-CD软件,对所设计的半螺旋型吸入室的三维模型进行了模拟计算,得到了吸入室的三维模拟结果图。并通过分析模拟的结果,对半螺旋型吸入室的设计做出了一些改进。

The shape of the suction chamber decides the inlet velocity distribution of the compression grade in the muhiphase pump, and affects the performance of the multiphase pump to a degree. By the advanced three-dimensional modeling software STAR-CD, the three-dimensional model of the half-helix suction chamber is simulated, and the three dimensional modeling results of the suction chamber is obtained. Through analyse the result, some improvement is given about the design of the half-helix suction chamber.
