由相干波推动的液滴串

Strings of droplets propelled by coherent waves

B. Filoux, M. Hubert, N. Vandewalle

摘要:

弹跳行走液滴由于其独特的波/粒子相互作用而具有迷人的特性。为了研究一维系统中的这种步行者,我们考虑了环形腔中的一个或多个液滴的情况。我们发现,在这种几何形状,步行液滴形成一串同步弹跳液滴,共享一个共同的相干波推动组的速度比单个步行者。该相干波的形成和液滴的集体行为由模型捕获。

英文摘要:

Bouncing walking droplets possess fascinating properties due to their peculiar wave/particule interaction. In order to study such walkers in a 1d system, we considered the case of one or more droplets in an annular cavity. We show that, in this geometry, walking droplets form a string of synchronized bouncing droplets that share a common coherent wave propelling the group at a speed faster than single walkers. The formation of this coherent wave and the collective behavior of droplets is captured by a model.
