| 摘 要： | 利用对色散方程的数值计算结果，分析了实际射流参数如射流速度，液体种类，喷孔半径，液体粘度，介质压力等对分别处于瑞利模式和泰勒模式下的液体射流的最不稳定频率及其最大扰动增长率的影响。结果表明，在不同的射流模式下，实际射流参数对液体射流最不稳定频率的影响是不同的。并对受激液体射流现象进行了初步试验观察。

| Abstract: | In this paper,by using the calculating results from the dispersion equation,the effects of injecting parameters on the most unstable frequency and its growth rate of a liquid jet both in Rayleigh mode and Taylor mode,have been studied in detail.These parameters include the jet velocity,liquid variety,nozzle diameter,liquid viscosity and gas pressure.Some experimental results have also been presented. |
