| 摘 要： | 再生式液体发射药火炮（ＲＬＰＧ）中，液体药在喷口处的流动特性影响到液体的雾化和燃烧，是控制ＲＬＰＧ内弹道过程的关键因素之一。该文针对园柱形轴对称射流建立了自由湍流射流模型，得到了射流的流速分布规律，利用该模型分析了射流的初始扩张角和完整射流核长度，并与实验结果进行了比较。

| Abstract: | In regenerative liquid propellant guns(RLPG),the breakup and atomization affect the control of RLPG interior ballistics.This paper presents a free turbulent liquid jet model ,and gains come the results of its veocity disturbance.With this model,the structures of the liquid jet atits initial stage are studied.The theoretically calculated value agrees with the experimental data. |
