Statistical description of anisotropic and inhomogeneous turbulence

Abstract

Statistical functions such as correlation functions and spectra yield length scales, each of which describes a certain aspect of the large-scale structure of turbulence.In this study not only statistics of wind fluctuations measured at the same place have been analysed but also statistics of fluctuations at different heights. Thus a spatial picture of the energy-containing and the momentum-transporting eddies has been obtained and some features of the momentum transport are described.
