Solar cycle dependence of scaling in solar wind fluctuations [PDF]

, 2008
In this review we collate recent results for the statistical scaling properties of fluctuations in the solar wind with a view to synthesizing two descriptions: that of evolving MHD turbulence and that of a scaling signature of coronal origin that ...

On the fractal nature of the magnetic field energy density in the solar wind [PDF]

, 2007
The solar wind exhibits scaling typical of intermittent turbulence in the statistics of in situ fluctuations in both the magnetic and velocity fields.

A Spectrum Correction Method Based on Optimizing Turbulence Intensity

Applied Sciences, 2021
Based on the classical spectral representation method of simulating turbulent wind speed fluctuation, a harmonic superposition algorithm was introduced in detail to calculate the homogeneous turbulence wind field simulation in space. From the view of the

Analyzing the Effects of a Basin on Atmospheric Environment Relevant to Optical Turbulence

Photonics, 2022
The performance of adaptive optics (AO) systems are highly dependent upon optical turbulence. Thus, it is necessary to have the appropriate knowledge of the spatiotemporal characteristics of optical turbulence strength.

Transport of Solar Wind Fluctuations: A Two-Component Model [PDF]

, 2011
We present a new model for the transport of solar wind fluctuations which treats them as two interacting incompressible components: quasi-two-dimensional turbulence and a wave-like piece.

Wake-tracking and turbulence modelling in computational aerodynamics of wind turbine aerofoils [PDF]

, 2009
This article addresses two modelling aspects of wind turbine aerofoil aerodyna-mics based on the solution of the Reynolds-averaged Navier–Stokes (RANS) equations.

Electron and proton heating by solar wind turbulence [PDF]

, 2009
Previous formulations of heating and transport associated with strong magnetohydrodynamic (MHD) turbulence are generalized to incorporate separate internal energy equations for electrons and protons. Electron heat conduction is included.

Wind observations from a forested hill: Relating turbulence statistics to surface characteristics in hilly and patchy terrain

Meteorologische Zeitschrift, 2018
This study investigates turbulence characteristics as observed at a 200 m tall mast at a hilly and complex site. It thereby concentrates on turbulence statistics, which are important for the site suitability analysis of a wind turbine.

Turbulence in the interstellar medium [PDF]

, 2014
Turbulence is ubiquitous in the insterstellar medium and plays a major role in several processes such as the formation of dense structures and stars, the stability of molecular clouds, the amplification of magnetic fields, and the re-acceleration and ...
