Abstract Experiments were preformed to measure the mass and size of secondary droplets splashed during liquid jet impingement onto a horizontal solid surface. To explore the effects of liquid hydraulic properties such as viscosity and surface tension, pure water, two aqueous solutions of glycerin, and two aqueous solutions of ethanol were used as the test solutions. Using the experimental data accumulated in this work, dimensionless correlation was developed for the splash ratio (ratio of the droplet splash rate to the jet flow rate). Here, it was assumed that the mass of secondary droplets splashed per impact can be expressed as a function of the impact Weber number and the Ohnesorge number. The correlations for the Sauter mean diameter and the size distribution of secondary droplets were also proposed. It was shown that the size distribution of the secondary droplets can be fitted with the log-normal distribution. Two parameters determining the log-normal distribution profile were correlated by the impact Weber number.

液体射流撞击水平固体表面产生二次液滴的实验研究

摘要 进行了实验以测量液体射流撞击水平固体表面时溅出的二次液滴的质量和大小。为了探索液体水力特性如粘度和表面张力的影响，使用纯水、两种甘油水溶液和两种乙醇水溶液作为测试溶液。使用在这项工作中积累的实验数据，开发了飞溅比（液滴飞溅速率与射流流速的比值）的无量纲相关性。在这里，假设每次撞击飞溅的二次液滴的质量可以表示为撞击韦伯数和奥内佐格数的函数。还提出了 Sauter 平均直径和二次液滴尺寸分布的相关性。结果表明，二次液滴的尺寸分布可以拟合对数正态分布。确定对数正态分布曲线的两个参数通过影响韦伯数相关联。
