闪烁场诱导润湿棘轮产生的液体输运
Liquid transport generated by a flashing field-induced wettability ratchet
摘要：
我们开发并分析了棘轮驱动的连续相宏观输运模型。该传输依赖于具有自由表面的液体膜的场诱导的去湿扩散循环，该自由表面基于液体-气体界面和基底的可切换的、空间不对称的、周期性的相互作用。这个概念是例示使用的演化方程的介电液膜下的非均匀电压。我们分析了棘轮循环的各个阶段对输运性质的影响。讨论了最大输运的条件和负载下的输运效率。
英文摘要：
We develop and analyze a model for ratchet-driven macroscopic transport of a continuous phase. The transport relies on a field-induced dewetting-spreading cycle of a liquid film with a free surface based on a switchable, spatially asymmetric, periodic interaction of the liquid-gas interface and the substrate. The concept is exemplified using an evolution equation for a dielectric liquid film under an inhomogeneous voltage. We analyse the influence of the various phases of the ratchet cycle on the transport properties. Conditions for maximal transport and the efficiency of transport under load are discussed.
