【摘要】 根据目前大型水轮机转轮存在的振动问题，本文用实验方法对HL160转轮尾水管中的水流流态进行了较详细的研究，其中包括尾水管水流压力脉动的测量以及逆流半径的测量。最后对实验结果进行了分析。更多还原

【Abstract】 Presently, there exist many vibration problems in large－scale hydraulic turbines. This paper researches the water flow state in the draft tube of HL160 runner, in which the following contents are included: the velocity field measurement in draft tube, the pressure pulsation measurement as well as the refluent radius measurement. Finally, the experimental results are analyzed.更多还原
