摘要
利用计算机进行各种流速模拟,分析尾水管不同工况下压力脉动幅、频域特性及能量分布情况,给出压力脉动对水轮发电机组的振动影响结果,以实现机组的优化设计.
Various flow velocities have been modelled. By analyzing the characteristic in frequency domain and the density distribution of energy in different opening of guide vane and discharge, the vibration of hydraulic turbine caused by pressure pulsation is obtained, which is useful for realizing the optimum design on water turbine.
