中文摘要：
本文通过可视化实验,对微通道内光热效应致相变驱动流体运动特性进行了研究,通过红外聚焦激光跟随微通道内液柱气液界面进行加热持续产生的蒸发冷凝-聚合过程对液柱进行连续驱动。实验研究了激光功率、加热点位置对相变过程中的界面行为、冷凝液滴分布、驱动速率的影响规律。结果表明,激光功率越高,光斑距离界面越近,液柱蒸发速率越大,蒸汽浓度高,冷凝液滴分布越密集,驱动流体流动速度越快。
英文摘要：
In this work,investigations on the photothermally induced phase change driving effect in a microchannel were carried out through visualized experiments.The focused IR laser was used to heat the liquid column and the liquid was pulled forward continuously through the evaporationcondensation-coalescence process induced by the photothermal effect.Results indicates that higher laser power leads to higher evaporation rate of the liquid body and more condensed droplets.Meanwhile,higher driving speed can be acquired with higher laser power and closer distance between the laser spot and the gas-liquid interface of the liquid column.
