Anomalous self-similarity in two-dimensional turbulence
Our velocity measurements on a quasi-two-dimensional turbulent flow in a rapidly rotating annulus yield an inverse cascade with E(k) ∼ k−2 rather than the expected E(k) ∼ k−5/3. The probability distribution functions for longitudinal velocity differences, δv(r) = v(x + r) − v(x), are self-similar (scale independent) but strongly non-Gaussian, which suggests that the coherent vortices play a sig...
متن کاملLarge eddy simulation of two - dimensional isotropic turbulence
Large eddy simulation (LES) of forced, homogeneous, isotropic, two-dimensional (2D) turbulence in the energy transfer subrange is the subject of this paper. A difficulty specific to this LES and its subgrid scale (SGS) representation is in that the energy source resides in high wave number modes excluded in simulations. Therefore, the SGS scheme in this case should assume the function of the en...
متن کاملA new subgrid eddy-viscosity model for large-eddy simulation of anisotropic turbulence
A new subgrid eddy-viscosity model is proposed in this paper. Full details of the derivation of the model are given with the assumption of homogeneous turbulence. The formulation of the model is based on the dynamic equation of the structure function of resolved scale turbulence. By means of the local volume average, the effect of the anisotropy is taken into account in the generalized Kolmogor...
متن کاملEddy viscosity and laminarization of sheared flow in three dimensional reduced magnetohydrodynamic turbulence
The effect of Alfvén waves on turbulent momentum transport is studied in three-dimensional reduced magnetohydrodynamic turbulence. A strong external uniform magnetic field B0 is assumed to be present orthogonal to both background shear flow and its inhomogeneity. Energy is injected into the fluid and/or magnetic field on small scales. It is shown analytically that eddy viscosity is reduced as 1...
متن کاملSpectral and hyper eddy viscosity in high-Reynolds-number turbulence
For the purpose of studying the spectral properties of energy transfer between large and small scales in high-Reynolds-number turbulence, we measure the longitudinal subgrid-scale (SGS) dissipation spectrum, defined as the co-spectrum of the SGS stress and filtered strain-rate tensors. An array of four closely spaced X-wire probes enables us to approximate a two-dimensional box filter by averag...
