Scaling Laws for Partially Developed Turbulence
نویسندگان
چکیده
We formulate multifractal models for velocity differences and gradients which describe the full range of length scales in turbulent flow, namely: laminar, dissipation, inertial, stirring ranges. The subsume existing inertial turbulence. In localized ranges turbulence is only partially developed, we propose scaling laws with exponents modified from their values. local regions, even within a fully developed not isotropic nor scale invariant due to influence larger structures (or absence). For this reason, that an important issue study can address. turbulence, flow be far universal, so standard become inapplicable. model proposed here serves as replacement. Details fitting parameters τ p ζ dissipation are discussed. Some behavior unexplained. theories verified by comparing high resolution simulation data.

Scaling Laws in Turbulence∗
The largely open problem of scaling laws in fully developed turbulence is discussed, with the stress put on similarities and differences with scaling in field theory. A soluble model of the passive advection is examined in more detail in order to illustrate the principal ideas. 1 LANGEVIN VERSUS NAVIER-STOKES Many dynamical problems in physics may be described by evolution equations of the type...
متن کاملScaling Laws in MHD Turbulence
We analyze the decay laws of the kinetic and magnetic energies and the evolution of correlation lengths in freely decaying incompressible magnetohydrodynamic (MHD) turbulence. Scale invariance of MHD equations assures that, in the case of constant dissipation parameters (i.e. kinematic viscosity and resistivity) and null magnetic helicity, the kinetic and magnetic energies decay in time as E ∼ ...
متن کاملMHD Turbulence: Scaling Laws and Astrophysical Implications
Turbulence is the most common state of astrophysical flows. In typical astrophysical fluids, turbulence is accompanied by strong magnetic fields, which has a large impact on the dynamics of the turbulent cascade. Recently, there has been a significant breakthrough on the theory of magnetohydrodynamic (MHD) turbulence. For the first time we have a scaling model that is supported by both observat...
متن کاملScaling laws and intermittency in phase turbulence
2014 We investigate numerically the statistical properties of the Kuramoto-SivashinskyTsuzuki model [1-3], which describes the phase fluctuations of extended systems near the transition to turbulence. This model has some similarities with hydrodynamic turbulence [4]. The time fluctuations exhibit an unexpected scaling corresponding to anomalous diffusion of the phase. Other results also point t...
