Structure of the most singular vortices in fully developed turbulence
S. I. Vainshtein, K. R. Sreenivasan
Using high Reynolds number experimental data, we search for most dissipative, most intense vortices. These structures possess a scaling predicted by log-Poisson model for the dissi…
Towards a dynamical theory of multifractals in turbulence
Victor Yakhot, K. R. Sreenivasan
Making use of the exact equations for structure functions, supplemented by the equations for dissipa tive anomaly as well as an estimate for the Lagrangian acceleration of fluid pa…
Sign-symmetry of temperature structure functions
Konstantinos G. Aivalis, Susan Kurien, Joerg Schumacher +1
New scalar structure functions with different sign-symmetry properties are defined. These structure functions possess different scaling exponents even when their order is the same.…
Critical Fluctuation of Wind Reversals in Convective Turbulence
Rudolph C. Hwa, C. B. Yang, S. Bershadskii +2
The irregular reversals of wind direction in convective turbulence are found to have fluctuating intervals that can be related to critical behavior. It is shown that the net magnet…
Gradient measure and extended self-similarity of the cosmic microwave background anisotropy
A. Bershadskii, K. R. Sreenivasan
Using the WMAP cosmic microwave background data it is shown that collisions between Alfven wave packets and the cascades generated by these collisions (the Iroshnikov model) can de…
Multiscale SOC in turbulent convection
K. R. Sreenivasan, A. Bershadskii, J. J. Niemela
Using data obtained in a laboratory thermal convection experiment at high Rayleigh numbers, it is shown that the multiscaling properties of the observed mean wind reversals are qua…
On the intermittency exponent of the turbulent energy cascade
Jochen Cleve, Martin Greiner, Bruce R. Pearson +1
We consider the turbulent energy dissipation from one-dimensional records in experiments using air and gaseous helium at cryogenic temperatures, and obtain the intermittency expone…
Intermittency and the passive nature of the magnitude of the magnetic field
A. Bershadskii, K. R. Sreenivasan
It is shown that the statistical properties of the magnitude of the magnetic field in turbulent electrically conducting media resemble, in the inertial range, those of passive scal…
"Clusterization" and intermittency of temperature fluctuations in turbulent convection
A. Bershadskii, J. J. Niemela, A. Praskovsky +1
Temperature time traces are obtained in turbulent thermal convection at high Rayleigh numbers. Measurements are made in the midplane of the apparatus, near the sidewall but outside…
