深窄峡谷区泄洪雾化及其影响的研究

On Atomizing Problems by Jumping Jet in Hydropower Station at Narrow and Deep Valley

在已有雾化研究成果的基础上，对挑流雾化问题进行了深入研究，建立了挑流雾化计算新的数学模型．该模型重点考虑了水舌段掺气散裂射流的特性，雾化流的雾流源量及雾流的侧向扩散等关键问题．为验证所建立数学模型的正确性，对乌江渡水电站原型观测资料进行了反馈分析．结果表明，所建立的模型具有较强的预报能力．

For atomizing problems by the jumping jet in hydropower station,a new mathematical model is established.ln this model the following problems are considered:the hydraulic characteristics of plane atomized jet;the quantity of atomized water;and the lateral diffusion of atomized flow.Comparing calculating results by the model with that of the prototype observation of Wujiangdu hydropower station,it shows that the model has fairly good predictive ability.
