摘要
水蒸汽喷射泵结构的优化对其工作性能有重要影响,通过适当的工作模型假设与简化,利用Fluent流体仿真软件对水蒸汽喷射泵工作的情况数值模拟计算,经过Gambit网格划分,Fluent求解,分析几个结构参数(喉径比、混合室入口直径、喉管长度)对水蒸汽喷射泵工作性能的影响规律,从而找出这些结构参数较合理的取值范围,使泵的工作性能达到最优化。
The optimization of hydro-steam ejector pump has an important influence on its performance. The fluid simulation software FLUENT can simulate the working performance of hydro-steam ejector pump by reasonable assumption and simplifica- tion of work model. Through the Gambit meshing and the FLUENT solution, the effect law of several structural parameters ( such as the throat diameter ratio, the inlet diameter of mixing chamber, and the throat length) on the working performance of steam jet pump is analyzd so as to find out the more reasonable scope of these structural parameters, thus to optimize the work- ing performance of pump.
