Meltwater transport and mixing layer growth near the ice--ocean interface
SofÃa Allende, Louis-Alexandre Couston, Simon Thalabard +1
Ice melting into saline water plays a fundamental role in the dynamics near the ice-ocean interface in polar oceans. The physics of ice melting involves a non-trivial interplay bet…
Perturbative anomalous exponents from Kolmogorov multipliers
Alexei A. Mailybaev, Simon Thalabard
We introduce a perturbative framework for anomalous scaling in turbulent transport based on multiplier statistics, rather than zero-mode calculations. We illustrate the approach us…
Dynamical cooling driven by self-similar fronts in the 2D nonlinear Schrödinger model
Jason Laurie, Simon Thalabard, Sergey Nazarenko
We analyze the dynamics towards partial thermalization and subsequent cooling in the defocusing two-dimensional nonlinear Schrödinger model, using direct simulations and insights…
Blowup driven by critical balance in a differential kinetic model of gravity wave turbulence
Daniel Schubring, Vladimir Rosenhaus, Simon Thalabard
We describe the blowup scenarios in a phase-parametrized differential approximation kinetic model (N-DAM), inspired by the physics of deep water surface gravity waves and recently…
Scale invariance of intermittency in LES turbulence
B. Magacho, S. Thalabard, M. Buzzicotti +3
Turbulent flows exhibit large intermittent fluctuations from inertial to dissipative scales, characterized by multifractal statistics and breaking the statistical self-similarity.…
Transport in multifractal Kraichnan flows: from turbulence to Liouville quantum gravity
André L. P. Considera, Simon Thalabard
We investigate the behavior of fluid trajectories in a multifractal extension of the Kraichnan model of turbulent advection. The model couples a one-dimensional, Gaussian, white-in…
