Abstract

The spectrum characteristics of turbulence such as period of fluctuation, frequency and amplitude of oscillation were discussed by using the method of spectral analysis of turbulence in this paper. The results show that the spectrum density in the range of low frequency is sharply variance with the distance from the windbreaks, but it follows the power index law of -5 / 3 and satisfies the theory of local isotropic turbulence in the range of high frequency. It also shows by connecting with Eulcrium autocorrelation analysis that there are small scalc, high frequency and short period of turbulence near the leesidc of windbreaks, but often large scale, low frequency and long period of turbulence far from the windbreaks.
