A note on the extension of the polar decomposition for the multidimensional Burgers equation
Uriel Frisch, Mark Mineev-Weinstein
It is shown that the generalizations to more than one space dimension of the pole decomposition for the Burgers equation with finite viscosity and no force are of the form u = -2 v…
Universal decay of scalar turbulence
M. Chaves, G. Eyink, U. Frisch +1
The asymptotic decay of passive scalar fields is solved analytically for the Kraichnan model, where the velocity has a short correlation time. At long times, two universality class…
Singularities and the distribution of density in the Burgers/adhesion model
U. Frisch, J. Bec, B. Villone
We are interested in the tail behavior of the pdf of mass density within the one and -dimensional Burgers/adhesion model used, e.g., to model the formation of large-scale struct…
Dispersive stabilization of the inverse cascade for the Kolmogorov flow
B. Legras, B. Villone, U. Frisch
It is shown by perturbation techniques and numerical simulations that the inverse cascade of kink-antikink annihilations, characteristic of the Kolmogorov flow in the slightly supe…
Lagrangian method for multiple correlations in passive scalar advection
U. Frisch, A. Mazzino, A. Noullez +1
A Lagrangian method is introduced for calculating simultaneous n-point correlations of a passive scalar advected by a random velocity field, with random forcing and finite molecula…
Intermittency in passive scalar advection
U. Frisch, A. Mazzino, M. Vergassola
A Lagrangian method for the numerical simulation of the Kraichnan passive scalar model is introduced. The method is based on Monte--Carlo simulations of tracer trajectories, supple…
