标题： Waves and instability in a one-dimensional microfluidic array

摘要： 在一维（1D）微流体阵列中的运动进行了模拟。 水滴被流动的油带动，排列成一行，由于它们的水动力相互作用，这些滴之间的间距呈现出波浪式运动，这种运动是纵向或横向的。 模拟产生的波谱与实验结果相符。 这种波浪式运动存在不稳定性，已被证实来源于相互作用势中的非线性。 不稳定性的发展是空间局部化的。 通过选择适当的关联函数，描述了纵向波和横向波之间的相互作用。 显示英文摘要

摘要： Motion in a one-dimensional (1D) microfluidic array is simulated. Water droplets, dragged by flowing oil, are arranged in a single row, and due to their hydrodynamic interactions spacing between these droplets oscillates with a wave-like motion that is longitudinal or transverse. The simulation yields wave spectra that agree well with experiment. The wave-like motion has an instability which is confirmed to arise from nonlinearities in the interaction potential. The instability's growth is spatially localized. By selecting an appropriate correlation function, the interaction between the longitudinal and transverse waves is described.
