摘要:

我们报告说,液体进行自我推进运动时,他们被放置在与热表面接触不对称(棘轮状)拓扑结构。当液体处于膜沸腾状态时,对于许多液体和在宽的温度范围内观察到泵送效应。我们建议,液体运动是由固体和液体之间的蒸汽流动所施加的粘性力驱动的。

英文摘要:

We report that liquids perform self-propelled motion when they are placed in contact with hot surfaces with asymmetric (ratchet-like) topology. The pumping effect is observed when the liquid is in the film-boiling regime, for many liquids and over a wide temperature range. We propose that liquid motion is driven by a viscous force exerted by vapor flow between the solid and the liquid.
