Fluctuation-dissipation relations and statistical temperatures in a turbulent von Kármán flow.
We experimentally characterize the fluctuations of the nonhomogeneous nonisotropic turbulence in an axisymmetric von Kármán flow. We show that these fluctuations satisfy relations, issued from the Euler equation, which are analogous to classical fluctuation-dissipation relations in statistical mechanics. We use these relations to estimate statistical temperatures of turbulence.
متن کاملSlow dynamics in a turbulent von Kármán swirling flow.
An experimental study of a turbulent von Kármán flow in a cylinder is presented. The mean flow is stationary up to a Reynolds number Re=10(4) where a bifurcation takes place. The new regime breaks some symmetries of the problem and becomes time dependent because of equatorial vortices moving with a precession movement. In the exact counterrotating case, a bistable regime appears and spontaneous...
متن کاملObservable dependence of fluctuation-dissipation relations and effective temperatures.
We study the nonequilibrium fluctuation-dissipation theorem (FDT) in the glass phase of Bouchaud's trap model. We incorporate an arbitrary observable m and obtain its correlation and response functions in closed form. A limiting nonequilibrium FDT plot is approached at long times for most choices of m. In contrast to standard mean field models, however, the shape of the plot depends nontriviall...
متن کاملBifurcation induced by the aspect ratio in a turbulent von Kármán swirling flow.
We evaluate the effect of the aspect ratio, i.e., the distance between the propellers H divided by the diameter D, on the slow dynamics of a von Kármán swirling flow driven by two propellers in a closed cylinder. We use a cell with a fixed diameter D but where the distance between the propellers can be turned continuously and where the inertia from the propellers can also be changed using diffe...
متن کاملFluctuation-dissipation relations for a nonlocal plasma.
A generalized version of the Callen-Welton fluctuation-dissipation formula that is nonlocal in space and time is derived. In a nonuniform plasma there appear significant differences between the fluctuations of the electrostatic field and those of the electron density, and the spatial inhomogeneities lead to an asymmetry with respect to the sign inversion of the frequency.
