Propagation characteristics of the vortex beam array through anisotropic non-Kolmogorov maritime atmospheric turbulence [PDF]
This study employs the power spectrum inversion method to generate the phase screens of atmospheric turbulence over the sea, the theoretical model of the vortex beam array emitted by a focusing system through anisotropic non-Kolmogorov maritime ...

High-fidelity database of supercritical homogeneous isotropic turbulence in the pseudo-boiling region [PDF]
Supercritical fluids operate above their critical point and are characterized by strong nonlinearities in the equation of state, highly non-ideal fluid behavior, and a tight coupling between thermodynamics and transport properties.

A Survey of Structure of Atmospheric Turbulence in Atmosphere and Related Turbulent Effects
The Earth’s atmosphere is the living environment in which we live and cannot escape. Atmospheric turbulence is a typical random inhomogeneous medium, which causes random fluctuations of both the amplitude and phase of optical wave propagating through it.

Is the Anisotropic Tilt Angle Necessary in the Turbulence Spectrum of Refractive-Index Fluctuations?
With the deepening of atmospheric turbulence research, scientists have discovered that the anisotropy of turbulence cells cannot be ignored. The anisotropic non-Kolmogorov turbulence model is more in line with the actual situation of atmospheric ...

Free space optical system performance for a Gaussian beam propagating through non Kolmogorov weak turbulence [PDF]
Atmospheric turbulence has been described for many years by Kolmogorov's power spectral density model because of its simplicity. Unfortunately several experiments have been reported recently that show Kolmogorov theory is sometimes incomplete to describe
