【摘要】 结合乌江构皮滩水利枢纽工程 ,用热膜流速仪在 1∶380的精细模型上量测了高拱坝挑跌流在水垫塘内的流速场 ,并由实验成果分析了淹没射流在水垫塘内的消能过程 ,计算了消能率。同时在 1∶1 1 0的工程模型上量测了水垫塘内的流速场 ,并与前者进行比较分析。更多还原

【Abstract】 Through a study on the energy dissipation of Goupitang Project on the Wu\|jiang River,the velocity field in the water cushion pool downstream skijump or drop was measured by Hot\|film anemometers on a fine model with a scale of 1∶380. Based on experimental results, the energy dissipation process in the Water cushion pool was analysed, and the rate of energy dissipation was calculated.the velocity field in the water cushion pool was also measured on a model with a scale of 1∶110. And the velocity field was compared with the fine model’s velocity field.更多还原
