摘要
本文采用数值模拟对交错形式的导叶叶片对于三代核电站反应堆冷却剂泵性能的影响进行研究。通过数值模拟和试验结果的比较验证了数值模拟的有效性。数值研究获得了不同交错叶片导叶方案下核主泵性能的变化。得到了水力性能曲线,轴向力曲线和压力脉动频谱图。数值结果表明:在额定流量下交错叶片稍微减少了水力效率,但对扬程、轴向力和功率几乎没有影响。交错叶片导叶有利于压力脉动,降低了水力部件内部压力脉动的振幅幅值,交错角3/4的方案是一个比较好的选择。
The effect of staggered diffuser vanes in a third- generation nuclear reactor coolant pump is numerically investigated. The numerical results are validated by comparison to experimental data. The performance change of the nuclear coolant pump with differently staggered vanes case was determined including the hydraulic performance curve, the axial force curve and the static pressure pulsation spectrogram. The simulation results show that in the rated flow, staggered vane reduce the hydraulic efficiency, but have no effect on the head, power and total axial force. Staggered vane with an angle of ? have the advantage to reduce the pressure pulsation amplitude.
