In this paper, a phenomenon of generation and transport of droplets is proposed, which is based on the dielectric liquid electroconvection induced by corona discharge. We placed the dielectric fluid on a conductive/nonconductive substrate, and then it broke apart to become many small droplets that move along the conductive microchannel. The behaviors of dielectric droplets were experimentally observed on different conductive microchannels in details. Spreading speeds and sizes of dielectric droplets were analyzed at different driving voltages and conductive microchannels. This work highlights a simple approach to produce and manipulate dielectric droplets along microchannels.
本文提出了一种基于电晕放电引起的介电液体电对流的液滴产生和传输现象。我们将介电流体放置在导电/非导电基板上，然后它会分裂成许多小液滴，这些小液滴沿着导电微通道移动。在不同的导电微通道上对介电液滴的行为进行了详细的实验观察。分析了不同驱动电压和导电微通道下介电液滴的铺展速度和尺寸。这项工作突出了一种沿微通道产生和操纵介电液滴的简单方法。
