倾斜侧吹气流在液体中运动行为的研究

Study on the behavior of a side-blown gas jet tilting in liquid

利用摄影方法对气流在液体中运动行为进行实验研究，在此基础上对所建立的倾斜侧吹气流在液体中的轨迹方程进行了修正．结果表明，射流在液体中垂直穿透深度的计算值与实侧值基本一致．此外还讨论了弗鲁德数和喷嘴倾斜角对射流垂直穿透深度的影响．

The experimental study on the behavior of the gas jet in liquid is made by photograph. On the basis of the experiment,the trajectory equation of a sideblown gas jet slanting in liquid i.s modified. The results show that the vertical penetrating depths calculated are in agreement with measured ones. In addition, the influences of Froude number and tilting angle of nozzle on the vertical penetrating depths are discussed.
