摘要：
In order to investigate the characteristic of gelled kerosene's secondary atomization, a high speed camera was applied to record and measure the breakup of gelled kerosene and kerosene droplet in the uniform air jet flow. Morphology and transition We of the droplet, impact of Oh on total breakup time and We on the maximum dimensionless diameter deformation ratio were obtained. The results indicate that in the range of test conditions, gelled kerosene and kerosene droplet has the similar vibrational, bag and multimode breakup mode, but not the same at the morphology and transition We. The total breakup time of kerosene droplet increases with the increasing of Oh, while the time of gelled kerosene increases first, then decreases and finally increases again with the increasing of Oh. The maximum dimensionless diameter deformation ratio of kerosene droplet increases first and then does not change with the increasing of We, while the maximum dimensionless diameter deformation ratio of gelled kerosene droplet increases first and then decreases with the increasing of We. Based on the test data, correlations for gelled kerosene and kerosene droplet were proposed to predict the impact of Oh on total breakup time and We on the maximum dimensionless diameter deformation ratio. © 2017, Editorial Department of Journal of Propulsion Technology.
