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.…
Surface quasigeostrophic turbulence: The refined study of an active scalar
Nicolas Valade, Jérémie Bec, Simon Thalabard
SQG describes the 2D active transport of a scalar field, such as temperature, which -- when properly rescaled -- shares the same physical dimension of length/time as the advecting…
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…
Non-unique self-similar blowups in shell models: insights from dynamical systems and machine-learning
Ciro Campolina, Eric Simonnet, Simon Thalabard
Strong numerical hints exist in favor of a universal blowup scenario in the Sabra shell model, a popular cascade model of 3D turbulence, which features complex velocity variables o…
