| 摘 要： | 对静止均匀浅水水域中的铅垂圆形单孔射流进行了试验研究,试验是在实验室的自制恒定水流循环系统中进行的。得到了水面的隆起高度与射流出口单位能量和相对水深的函数关系;验证了隆起高度分布具有自相似性,并给出其统一表达式;借助于三维测速仪,得到了射流流速的横断面分布、射流中线流速的衰减规律和流场的流函数等值线。

| Abstract: | This paper presents an experimental study of turbulent jets discharged vertically through a single circular submerged pipe into a large of stagnant non stratified water of finite depth. The experiments were carried out in the laboratory facilit ies consisting of a closed system capable of maintaining steady state conditions. The maximum water surface elevation is obtained for numerous flows,as function of jet energy flux and discharge depth The similarity of water surface elevation distribution was found,and its formula was got. The distribution of velocity in cross section and the rate of change of centerline velocity were obtained by the micro ADV system. |
