Turbulence and Tsallis Statistics
Toshiyuki Gotoh, Robert H. Kraichnan
Fully-developed incompressible Navier-Stokes turbulence in three dimensions is a dissipative dynamical system that exhibits strong departure from absolute equilibrium. Nevertheless…
Note on Forced Burgers Turbulence
Robert H. Kraichnan
A putative powerlaw range of the probability density of velocity gradient in high-Reynolds-number forced Burgers turbulence is studied. In the absence of information about shock lo…
Burgers Turbulence with Large-scale Forcing
Toshiyuki Gotoh, Robert H. Kraichnan
Burgers turbulence supported by white-in-time random forcing at low wavenumbers is studied analytically and by computer simulation. It is concluded that the probability density Q o…
Statistics of Dissipation and Enstrophy Induced by a Set of Burgers Vortices
Guowei He, Shiyi Chen, Robert. H. Kraichnan +2
Dissipation and enstropy statistics are calculated for an ensemble of modified Burgers vortices in equilibrium under uniform straining. Different best-fit, finite-range scaling exp…
Passive Scalar: Scaling Exponents and Realizability
Robert H. Kraichnan
An isotropic passive scalar field advected by a rapidly-varying velocity field is studied. The tail of the probability distribution for the difference in acros…
Far Dissipation Range of Turbulence
Shiyi Chen, Gary Doolen, Jackson R. Herring +3
The very small scales of isotropic, Navier-Stokes turbulence at Reynolds number are studied by high-resolution direct numerical simulation (DNS) and by integ…
