    摘要:

    为探究射流对有压管道内主流压力场的影响,就矩形管道内流体汇入单股射流进行了实验研究。射流入射方向与主流之间的角度为90°,射流速度为主流速度的1~6倍。实验结果表明,在入射口附近存在1个向下游偏斜的射流核心区;随着入射流体的进入,核心区内的压力略有增加;核心区外,管道内流体压力产生较大幅度的提升,该提升量与射流速度的二次方成正比,与主流速度无关。

    Abstract:

    An experimental investigation is performed on a single jet issuing into a flow in a pipe. The pressure of the flow in pipe is measured under the condition when there is a right angle between the jet and the mainstream and the velocity of the jet is 1 to 6 times of the mainstream. The results show that, there exists a jet core with skewing downstream near the entrance port; the pressure in that core increases slightly with the fluid incidence. Outside the core, the pressure of the flow inside the pipe increases significantly; the pressure increment is correlated with the velocity of the jet quadratic dependence.
