| 摘 要： | 多层水股在水垫塘内的流动特征及其各水股间的干扰、碰撞和动水垫效应等对探明水垫塘的消能机理和体型优化设计具有重要的意义．本文利用激光片光源和荧光染色液技术，对静水和动水垫中的射流进行了流场显示试验，并通过射流在动水中的流动特征和淹没冲击射流理论，分析了多层水股在水垫塘内的流动机理和动水垫效应，导出的有关公式得到了试验资料的验证

| Abstract: | Flow characteristics of multi jet impinged into a plunge pool are investigated experimentally.By using the sheet laser light and tracing technology,flow visualization is carried out.The experimental result is in accordance with the theoretical analysis.It shows that the effect of flowing water cushion is significant in reducing the impact on the plunge pool bottom.Some hydraulic formulas deduced are verified by experimental data. |
