摘要
以150×100LN-32型螺旋离心泵为研究对象,通过试验研究了此泵的外特性,并得出了一些结论。采用CFD软件Fluent,选用标准k-ε模型,计算了该泵的三维内部流场。通过对该泵内部流动速度、压力分布与捕捉到的流动冲击、二次流、回流等重要现象的分析,给该泵的性能改善与改进提供可靠的信息。通过分析,提出了在设计螺旋离心泵时的一些改进措施。
The exterior performances of a 150×100LN-32 helix centrifugal pumps were studied experimentally.The three dimension interior flow field was simulated by means of computional fluid dynamics （CFD） software, Fluent6.0 with standard K-ε model. Useful information for the performance improvement was got from the distribution of inner flow velocity and pressure, flows impact, secondary flow and recirculation in the helix centrifugal pump. Some proposes some methods for performance improvement in designing the helix centrifugal pumps were suggested.
