| 摘 要： | 将粘性气体中的三维粘性圆柱形液体射流分裂与雾化机理，应用到喷雾特性的研究中．确立了喷嘴出口处未受扰液核长度及喷雾平均滴径的计算方法．本文得到的平均滴径与实验的统计值相吻合．此外，数值计算还发现高速射流的雾化过程主要是由短波长的扰动波引起的．

| Abstract: | The mechanism of breakup and atomization of a three-dimensional cylindrical viscous liquid jet in a viscous gas was applied to predicting characteristic parameters of fuel sprays. An approximated method for calculating the intact liquid length and the mean droplet diameter of the spray was presented. The computed results agreed with experimental data from the literature. Furthermore the numerical simulation revealed that the atomization of a high speed liquid jet attributed to the growth of the disturbances with short wave lengths. |
