Abstract:

Flood discharge atomization of high dam projects will have possible negative impact on the hydropower station operation, traffic safety, surrounding environment, and even the stability of the downstream bank slope. Researchers have done much work in this regard, and meanwhile there is still much work to do because of its significance and complexity. This paper presents a full scale review on current study on this issue, summarizes the cognition on its damage, the forming mechanism of the atomization, and the comparison of different experimental and numerical research results. It’s proposed that two aspects should be focused on in the future study: first, advanced measuring equipment and methods should be imported and invented to obtain more particular and accurate information; second, properties of the atomization source should be paid more attention to.

Key words: flood discharge atomization, research progress, scale effect, model test, numerical forecast
