泄洪雾化源区降雨强度分布特性试验研究
Experimental Research on the Rainfall Intensity in the Source Area of Flood Discharge Atomization
摘要
Abstract
The heavy rainfall and mist flow induced by flood discharge atomization of high dam projects have negative effect on the hydropower project and its surrounding environment.Previous researches were focused on the rainfall intensity distribution on the downstream banks,while the source area of the atomization is still not well revealed.Through generalized hydraulic model tests,the rainfall intensity in the atomization source in the progress of a deflecting flow nappe dropping in the downstream water were measured under different hydraulic conditions.The horizontal distribution was analyzed,and the causes of atomization sources and rainfall intensity distribution in the upstream,downstream and side regions around the nappe drop location were determined.The variations of nappe drop location and rainfall intensity distribution along with the change of water flow and head difference were also preliminarily investigated.关键词
