【摘要】 设计一种用于研究水滴碰撞过程的小型垂直风洞,采用高速摄影技术可分析水滴碰撞后出现的各种现象。实验的结果表明碰撞后可出现:(1)合并,包括在尾流区的合并,指出连接结构以及碰撞角和碰撞速度的影响;(2)反跳;(3)暂时合并;(4)破碎,包括(?)铃式和袋式破碎以及破碎后大、小水滴之间的再碰撞。更多还原

【Abstract】 A small-sized vertical tunnel is devised to stady the collision process of two waterdrops. The data, obtained by high-specd photograph technique, indicate: (a) coalescence after collision, taking into account the influencesof wake, collision angle and collision velocity, ( b) bounce after collision, (c) temporary coalescence after collision, (d) breakup after collision, including dumb-bell and bag breakip and the re beeweet tv brokeneao drops .更多还原
