使用商业软件通过 CFD 评估空化诱导轮的传递矩阵和非稳态空化特性、空化顺应性和质量流量增益因子。首先通过在不同流量和入口空化数下进行稳定计算，获得空化顺应性和质量流量增益因子的准稳态值。然后进行非稳态计算以确定传输矩阵和空化特性。结果与实验进行了比较，证明了计算的有效性。
The transfer matrix and unsteady cavitation characteristics, cavitation compliance and mass flow gain factor, of cavitating inducer were evaluated by CFD using commercial software. Quasi-steady values of cavitation compliance and mass flow gain factor were obtained first by using steady calculations at various flow rate and inlet cavitation number. Then unsteady calculations were made to determine the transfer matrix and the cavitation characteristics. The results are compared with experiments to show the validity of calculations.
