Couder等人(Nature,vol.437(7056),2005,p.208)发现,在振动浴上行走的液滴具有某些以前被认为是量子系统所独有的特征。这些毫米级的液滴与它们的法拉第波场同步,形成宏观的导频波系统。在本文中,我们利用这一事实,即产生的波几乎是单色的,并提出了一个流体动力学模型,能够定量捕捉弹跳滴和可变地形之间的相互作用。我们表明,我们的简化模型是能够重现一些重要的实验涉及滴地形相互作用,如非镜面反射和单缝衍射。
Couder et al. (Nature, vol. 437 (7056), 2005, p. 208) discovered that droplets walking on a vibrating bath possess certain features previously thought to be exclusive to quantum systems. These millimetric droplets synchronize with their Faraday wavefield, creating a macroscopic pilot-wave system. In this paper we exploit the fact that the waves generated are nearly monochromatic and propose a hydrodynamic model capable of quantitatively capturing the interaction between bouncing drops and a variable topography. We show that our reduced model is able to reproduce some important experiments involving the drop–topography interaction, such as non-specular reflection and single-slit diffraction.
