摘要
利用高速水力学国家重．或实验室的激光测速仪对三种不同粗糙度、两种反弧半径的溢流反弧段的水流流速进行了测量，对边界居特性进行了分析研究。试验分析表明，水流流态、壁面粗糙度和壁面曲率对边界居特性有明显的影响。
The laser velocity measuring meter of the National Key Laboratory of High-VelocityHydraulic Mechanics is used to three kinds of roughnesses and flow velocity of running water inthe section of spillway buckets with two kinds of bucket radias, and also, the characteristics ofboundary layers are analysed and studied in this paper. The testing analysis shows that the water'flow patterns, wall roughness and wall curvature have an apparent effect upon the characteristicsof the boundary layers.
