摘要
以某特殊用高抗汽蚀泵为研究模型,采用CFD数值模拟技术,基于RNG的k-ε湍流模型和SIMPLEC算法,对泵内部流场进行定常数值模拟,并进行了汽蚀计算。对比试验结果和数值模拟结果得出结论,数值计算可以较好的预测泵的汽蚀性能,为高抗汽蚀泵的设计和研发提供基础。
This paper studies on a high resistant cavitation model of the special pump. By CFD numerical simulation technology, this paper simulates the flow field in the pump and calculates the cavitation performance based on SIMPLEC algorithm and the k-ε turbulence model of RNG. Through comparing the experimental results, the numerical simulation is able to predict pump cavitation performance. It provides the basis for design and development of high anti-cavitation pump.
