  • 摘要: 泄洪雾化影响的研究和预测目前仍然以大比尺模型试验研究为主,但模型缩尺效应是制约这一方法准确预报泄洪雾化影响范围及程度的关键因素。根据乌江渡水电站泄洪雾化原型观测资料,通过系列模型试验研究,分析了水流Re和We数对泄洪雾化降雨强度的影响,对泄洪雾化雨强的模型试验值与原型观测结果之间的相似关系进行了探索,研究了雾化降雨影响区域的不同比尺模型试验测试结果之间的几何相似性。
    Abstract: A series model method is adapted to the preliminary study of scale effect of discharge atomization-rainfall (A-R) model with the field observation result of discharge atomization for Wujiangdu power station.The effect of Re and We numbers of flow on the A-R intensity is analyzed.A conversion relationship of A-R intensity between prototype and model results is developed.The similitude criteria of the A-R range followed by discharge atomization model is discussed,and the conclusion is achieved that the surface tension of discharge A-R model is ignored when We number is larger than 500.
