Faraday surface ripple forced 2D turbulence

Abstract

We report new experimental results which support that the particle motion on the surface of Faraday waves share similarities with the fluid motion in 2D turbulence [1]. These results extends the original findings reported in [2]. Since it is clear that the particle motion is not strictly 2D and some of the 2D turbulence theory' s assumptions are violated in Faraday waves, we investigate how robust this analogy is by exploring in depth several features of 2D turbulence such as: the −5/3 kolmogorov scaling for the energy spectrum of the velocity fluctuations, the spectral localness of the energy injection, the 3rd order velocity structure function.
