摘要：有关射流对撞的流动结构研究目前尚未有公开的文献技导，本文在这方面做了一些初步的实验研究。实验过程是利用两股淹没式轴对称水射流进行对撞实验，用激光荣光法和氢气泡法进行流场显示，通过大量的实验及结果分析，对气流粉碎中的射流对撞过程和流动结构提出了一些定性的认识，文后附了一个应用实例。

Abstract:There is no research work about the flowing structure of two jets collisionreported in the public documents at present. In the study for the flowing structure of the two jetscollision, two streams of submerged round liquid jets were used,meanwhile laser-flourometrymethod and hydrogen-bulb method were used for flow visualization.Through a great deal ofexperiments,fundamental understanding about the flowing structure of two jets collision wasobtained. The stability of the intersection plane of collision and the relation to Re number of thejet entrance was also analyzed in the paper.
