单气泡破裂产生膜液滴空间分布实验研究

本文研究了常温、常压条件下自由液面单气泡破裂产生的膜液滴现象。利用染色液滴撞击熟宣纸表面不洇散特性,加工宣纸纸筒进行稀释墨水中气泡破裂产生膜液滴空间分布实验,并通过后续图片扫描及编写Matlab图像处理程序获得膜液滴在圆柱纸筒上的尺寸分布、空间分布信息。通过改变实验条件,讨论分析气泡尺寸及纸筒半径对膜液滴空间分布结果的影响,获得了常温、常压条件下自由液面单气泡破裂产生膜液滴空间分布规律。

Experimental Research on Space-distribution of Film Drops Produced by Single Bubble Bursting

The phenomenon of the film drops produced by the single bubble bursting at a free water surface was researched. The rice paper cylinder, which was made under special technique process and did not soak the ink at the surface, was used to conduct the space distribution experiment of the film drops produced by bubble bursting in the ink water. The size and space distributions of film drops on the different radius cylinders were obtained by scanning the picture and using the image processing code programmed in Matlab. With experiment conditions changing, the impact of the bubble size and the radius of the rice paper cylinder on space distributions of film drops was discussed. The rule of the space distribution of film drops produced by single bubble bursting at a free water surface was obtained under the normal temperature and pressure condition.
