摘　　要：为研究夏特电站水轮机导叶的磨损情况,采用固液两相标准k-ε湍流模型对水轮机全过流通道的沙水流动特性进行数值模拟,对该电站水轮机活动导叶进行泥沙磨损试验,得到了活动导叶的磨损规律,并通过试验和数值结果得到导叶磨损率计算公式。结果表明:磨损严重处为活动导叶头部、尾部及背面。In order to study the wear of the turbine guide vanes at the Xiate hydropower station,the solid-liquid two-phase standard k-εturbulence model was adopted to numerically simulate the flow characteristics for sediment and water in the full flow passage of hydraulic turbine.Meanwhile,a sediment abrasion test of the turbine guide vane was carried out,so as to obtain the wear rule of the guide vane,as well as the calculation formula of wear rate for guide vane through experimental and numerical results.Results show that the severely worn parts are the head,tail and back of the guide vane.
