摘　　要：本文使用CFD分析软件FLUENT,对波黑优乐高电站在最高水头、额定水头及最小水头三种运行工况下进行了全流道数值模拟。通过分析,获得了三种工况下全流道的压力分布、速度分布、叶片力矩值以及叶片表面应力分布。然后进行流固耦合计算,将叶片表面应力分布加载至转轮叶片表面,实现了转轮的刚强度分析。通过全流道CFD分析及转轮刚强度计算结果表明,三种工况下流道压力及速度分布合理、水轮机出力满足额定功率的设计值,转轮强度足够,能够满足优乐高电站安全稳定运行。In this paper, CFD analysis software is used to simulate the full channel of ULOG Hydropower Station under three operating conditions: maximum head, rated head and minimum head. Through the analysis, the pressure distribution, velocity distribution, blade torque and blade surface stress distribution of the full channel under three working conditions are obtained. Then, the fluid solid coupling calculation is carried out, and the stress distribution on the blade surface is loaded onto the blade surface of the runner to realize the stiffness and strength analysis of the runner. The results of full channel CFD analysis and runner stiffness and strength calculation show that under the three working conditions, the pressure and speed distribution of the channel are reasonable, the turbine output meets the design value of rated power, and the runner strength is sufficient to meet the safe and stable operation of ULOG Hydropower Station.
