面向主动微流控：具有浮动分子机器的薄液膜中的界面turbulence
Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines
摘要：
被认为是与浮动的活性蛋白质机器的液体薄膜。机器内的循环机械运动，代表微观游泳者，导致分子推进力施加到空气-液体界面。我们发现，当机器的能量供应率超过阈值时，平坦的界面变得线性不稳定。由于这种不稳定性，建立了界面湍流的制度，其特征在于不规则的行波和传播的机器集群。这种非线性政权的数值研究进行。讨论了实验观测不稳定性的条件。
英文摘要：
Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsion forces applied to the air-liquid interface. We show that, when the rate of energy supply to the machines exceeds a threshold, the flat interface becomes linearly unstable. As the result of this instability, the regime of interface turbulence, characterized by irregular traveling waves and propagating machine clusters, is established. Numerical investigations of this nonlinear regime are performed. Conditions for the experimental observation of the instability are discussed.
