Large-scale multifractality and lack of self-similar decay for Burgers and 3D Navier-Stokes turbulence
Takeshi Matsumoto, Dipankar Roy, Konstantin Khanin +2
We study decaying turbulence in the 1D Burgers equation (Burgulence) and 3D Navier-Stokes (NS) turbulence. We first investigate the decay in time of the energy in Burgul…
