摘　　要：采用DES数值模拟方法对水泵水轮机驼峰区的多个工况点进行了非定常数值模拟,并对驼峰区的压力脉动幅值和频率进行了评估,同时对驼峰区的特性及流态进行了分析。经试验对比,DES数值模拟方法能够对驼峰区压力脉动的频率做出较为准确预估,同时能对幅值进行准确的预测。Unsteady numerical analyses of several operation condition points of a mixed flow pump turbine in its hump zone are carried out with the DES numerical simulation method.The amplitude and frequency of the pressure fluctuation in the hump zone are evaluated.The characteristics and flow patterns of the hump zone are analyzed.Comparison with the experiment results shows that the DES numerical simulation method can accurately predict the frequency and amplitude of the pressure fluctuation in the hump zone.
