Eric Falcon, Sebastien Aumaitre, Claudio Falcon, Claude Laroche,, Stephan Fauve
TL;DR
This paper investigates the large fluctuations in energy flux within wave turbulence, revealing a complex probability distribution with significant deviations from the mean, modeled effectively by a Langevin approach.
Contribution
It introduces a simple Langevin model to qualitatively explain the asymmetric exponential tails of the energy flux PDF in wave turbulence.
Findings
Energy flux fluctuations are much stronger than the mean.
The PDF of energy flux has a most probable value near zero.
The model captures the asymmetric exponential tails of the PDF.
Abstract
We report that the power driving gravity and capillary wave turbulence in a statistically stationary regime displays fluctuations much stronger than its mean value. We show that its probability density function (PDF) has a most probable value close to zero and involves two asymmetric roughly exponential tails. We understand the qualitative features of the PDF using a simple Langevin type model.
