描述了消力池底板上射流冲击形成的压力脉动场;给出了对应于一定范围内的流速、消力池长、池深、出口设施的形式及射流直径等物理量的时均及脉动量的数据;详细比较分析了圆形射流的数据与其他宽矩形溢流水舌和矩形闸下射流的数据;研究了射流入池前破碎程度的影响和消力池中夹杂空气的作用;最后通过案例分析说明结果的实用性。
Describes the pressure pulsation field formed by jet impingement on the floor of the stilling pool and gives the time-averaged and pulsatile quantities corresponding to the flow rate, the length of the stilling pool, the pool depth, the form of the outlet facilities and the jet diameter etc. within a certain range The data of circular jet were compared with the data of other wide rectangular overflow water tongues and the lower jet of rectangular gate. The influence of the degree of crushing before the jet flow into the pool and the role of the mixed air in the stilling pool were studied. Finally, Describe the practicality of the result.
