Velocity fluctuations in forced Burgers turbulence | | J.-P. Bouchaud

1 Jul 1996 | | Subject: | Condensed Matter; Chaotic Dynamics | cond-mat chao-dyn hep-th nlin.CD | | Abstract: | We propose a simple method to compute the velocity difference statistics in forced Burgers turbulence in any dimension. Within a reasonnable assumption concerning the nucleation and coalescence of shocks, we find in particular that the `left’ tail of the distribution decays as an inverse square power, which is compatible with numerical data. Our results are compared to those of various recent approaches: instantons, operator product expansion, replicas. | | Source: | arXiv, cond-mat/9607006 | | Services: | Forum | Review | PDF | Favorites | |
