Experimental research on the droplet impacting on the liquid film

摘要: 实验显示了液滴撞击物体表面液膜后产生水花、发生飞溅,特别是产生"钟形"水花等的流动现象.根据实验结果,探讨了液滴冲击速度、液体黏性、表面张力、液滴直径和液膜厚度等对液滴冲击后产生的流动现象,以及液膜形状演化的影响,分析了观测到的鲜有文献报道的液滴撞击液膜后产生"钟形"水花的现象.

Abstract: The flow phenomena such as spray,splash and especially the bell-like spray happening after a droplet impacts on the liquid film are observed in experiment.The relationship between the flow phenomena and the diameter and speed of the droplet,and the viscosity,the surface tension and the thickness of the film are probed.The condition for bell-like spray brought about after the collision of the droplet on the film is discussed.
