摘要
利用计算流体力学(CFD)数值模拟方法对某长轴泵在不同运行工况下的参数进行了全面性能分析,在此基础上进行改型设计,达到了用户提出的参数要求。结果表明,CFD数值分析法能准确预测水泵在各种工况下的内部流动状态及性能参数,为进一步改型提供指导。
This paper generally analyzed the performance of the long axis water pump by means of CFD method; the results include the parameters such as head, efficiency, and the remodeling will be made based on the analysis to satisfy the user requirement. The results indicate that it can accurately forecast the inflow states and performance parameters in different operating conditions by means of CFD method, and provide the direction for further remodeling. The remodeling result satisfies the user＇s requirement.
