Universality in fully developed turbulence.
We extend the numerical simulations of She et al. (1993)] of highly turbulent ow with 15 Taylor-Reynolds number Re 200 up to Re 45 000, employing a reduced wave vector set method (introduced earlier) to approximately solve the Navier-Stokes equation. First, also for these extremely high Reynolds numbers Re , the energy spectra as well as the higher moments { when scaled by the spectral intensit...
متن کاملCritical Exponents and Universality in Fully Developed Turbulence
Multi-fractal model for hydrodynamic fully-developed turbulence (FDT) has been used to provide a detailed structure for the critical exponent σ describing the scaling form of energy (or enstrophy) dissipation rate ǫ (or τ) that appears to exhibit an interesting universality covering radically different hydrodynamic FDT systems. This result also appears to provide a consistent framework for clas...

We extend the numerical simulations of She et al. [Phys. Rev. Lett. 70, 3251 (1993)] of highly turbulent flow with 15 ≤ Taylor-Reynolds number Reλ ≤ 200 up to Reλ ≈ 45 000, employing a reduced wave vector set method (introduced earlier) to approximately solve the Navier-Stokes equation. First, also for these extremely high Reynolds numbers Reλ, the energy spectra as well as the higher moments –...
متن کاملGeneralized Additive Entropies in Fully Developed Turbulence
We explore a possible application of the additive generalization of the BoltzmannGibbs-Shannon entropy proposed in [A. N. Gorban, I. V. Karlin, Phys. Rev. E, 67:016104 (2003)] to fully developed turbulence. The predicted probability distribution functions are compared with those obtained from Tsallis’ entropy and with experimental data. Consequences of the existence of hidden subsystems are ill...
