Spontaneous stochasticity and anomalous dissipation in collapsing wave turbulence
Wandrille Ruffenach
We study a focusing Majda--McLaughlin--Tabak type equation undergoing finite-time wave collapse. This singularity terminates the classical smooth solution and opens a post-blowup r…

A spatio-temporal random synthetic turbulent velocity field: The underlying Gaussian structure
Matthieu Chatelain, Júlia Domingues Lemos, Wandrille Ruffenach +5
We develop, simulate and extend an initial proposition by Chaves et al. concerning a random incompressible vector field able to reproduce key ingredients of three-dimensional turbu…
