摘要
基于惯性力破碎液柱,设计出一种简易均匀单分散液滴流发生器。利用该发生器研究了不同给液高度、不同喷嘴直径等条件下的液滴生成特性。通过高速相机对生成液滴进行记录,辅以配套的图像处理软件,获取液滴的相关参数,发现单分散液滴的液滴间距随相对高度的变化呈现峰值变化规律,同时生成液滴的直径随喷嘴的外径变化而改变,而给液高度的变化对液滴的生成直径没有影响。
A simple mono-disperse droplet stream generator is designed based on the liquid column breakup by inertial force. The effects of relative height and nozzle diameter of this generator on the characters of droplets are studied. The droplets formation is recorded by high speed camera. The related parameters of droplets are provided with the matching image processing software. The distance between droplets presents the variation of peak with the change of relative height. The droplet diameter is influenced by the outer diameter of injector. Moreover, different relative height doesn＇t change the droplet diameter.
