挑流水舌雾化的研究

Study on Jet Nappe Atomization

通过对已建大型水电站挑流水舌雾化的原型观察，本文论述了高水头的挑流水舌的形态仍基本遵循重力相似规律。本文提出的原型观察结合图象处理研究雾化强度分布的方法方便可靠，用以预报在建水电站的挑流雾化时有利于工程建设。本文最后从水舌雾化角度，对新型消能工进行了初步评价。

Through the prototype observation of jet nappe atomizaton of a large hydropower station which has been built,this paper expounds that the jet nappe shape of the high water head still adheres to the gravity similarity law basically. Themethod connected the prototype observation with the image process which is suggested in this paper for studying the distribution of the atomization intensity is covement and reliable. It is also usefull to the engineering construction in predicting the jet-flow atomization of the hydropower station which are being built. Finally, the paper makes a tentative evaluation for the new type hydraulic energy dissipators from the view of jet nappe atomization.
