Dual non-Kolmogorov cascades in a von Kármán flow
EPL (Europhysics Letters), 2012The experimental spatial power spectrum of the velocity fluctuations in a von Karman flow is measured, in a wide range of Reynolds numbers, 102 105.

Phase compensation in non-Kolmogorov atmospheric turbulence
Optik, 2014Abstract Zernike polynomial decompositions are used for investigating phase distortion induced by atmospheric turbulence in optical systems. Closed-form expression of the Zernike-coefficient variances is derived. The finite size of the receiver aperture is analyzed using the filter function which is also particularly effective in the theoretical ...

Optical propagation in non-Kolmogorov atmospheric turbulence
SPIE Proceedings, 1995Several observations of atmospheric turbulence statistics have been reported which do not obey Kolmogorov's power spectral density model. These observations have prompted the study of optical propagation through turbulence described by non-classical power spectra.

Non-Kolmogorov’s and Kolmogorov’s Solitonic Hydrodynamical Turbulence
Imaging and Applied Optics 2014, 2014The experimental spectrums for the non-Kolmogorov’s and Kolmogorov’s turbulence are presenting as a sums of spectrums of several coherent structures. Therefore the coherent structure (soliton solution of the hydrodynamic equations) is the basic structural element of turbulence.

Imaging and communications through non-Kolmogorov turbulence
SPIE Proceedings, 2009At present, system design usually assumes the Kolmogorov model of refractive index fluctuation spectra in the atmosphere. However, experimental data indicates that in the atmospheric boundary layer and at higher altitudes the turbulence can be different from Kolmogorov's type.

A General Mathematical Model For Non-Kolmogorov Turbulence
Imaging and Applied Optics, 2013We present a power spectral density model of index of refraction, including power law relations within finite bands, and impulses denoting energy concentrations. We then discuss some resulting equations, without resorting to Kolmogorov assumptions.

Non-Kolmogorov dissipation in a turbulent planar jet
Physical Review Fluids, 2018Adopting Lie symmetry group theory both Kolmogorov and non-Kolmogorov scaling and dissipation laws are explored theoretically for a turbulent planar jet. We find that the jet entrainment coefficient varies with streamwise distance when non-Kolmogorov scaling laws hold.

Non-Kolmogorov Probability Theory
1997Now, the situation in the theory of probability is more or less the same as it was in geometry in 19th century. Many scientists understand that the Kolmogorov axiomatics [174] (1933) of the modern theory of probability cannot describe all probabilistic phenomenon which are observed in nature.

Multimode Laser Beam Scintillations in Non-Kolmogorov Turbulence
IEEE Journal on Selected Areas in Communications, 2015Employing the Rytov solution, the scintillation index at the origin of the receiver plane is evaluated in non-Kolmogorov weak atmospheric turbulence when multimode laser incidence is used. The solution presented can be used when the multimode is composed of even modes. The novelty of this work lies in the theoretical combination of multimode laser beam

Non-Kolmogorov Probability and Quantum Physics
1997We have already seen that the EPR definition of elements of reality is based on two purely mathematical elements: real numbers and real probabilities. As the Kolmogorov probability theory is the main mathematical model for describing real probabilities, we can speak of Kolmogorov physical reality.
