Development of Suspending Method of Large Free Droplet Using Optical Tweezers System

虽然有许多实验观察燃油液滴的蒸发或燃烧作为喷雾燃烧的基本模型，但在实验中，液滴通常是由纤维悬浮的，纤维对蒸发的影响是无法消除的。本文报道了一种用光钳代替悬挂器的非接触式液滴悬浮方法的基本实验。开发了雾化和观测系统以及悬浮法。利用光钳系统成功地实现了各种燃料液滴的悬浮。

Although there are many experiments to observe vaporizing or burning fuel droplets as a basic model of spray combustion, the droplets are usually suspended by a fiber in the experiments and the effect of fiber on vaporization cannot be eliminated. This study reports basic experiments of a noncontact droplet suspension method using optical tweezers instead of the suspender. Atomization and observation systems are developed as well as suspension method. As a result, various fuel droplets was successfully suspended by optical tweezers system.
