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 regenerat ive liquid propellant guns( RLPG) , the breakup and atomization af fect the cont rol of RLPG interior ballistics. T his paper presents a free turbulent liquid jet model , and g ains come the results of its veocity disturbance. With this model, the st ructures of the liquid jet at it s init ial stage are studied. T he theoret ically calculated value agrees w ith the ex perimental data.
