Validation of Randomness of Wind Field Simulation Algorithm Based on Random Fourier Spectrum

Abstract:

It is investigated whether random simulated wind field can reflect the random characteristics of the given wind environment on the basis of wind field simulation algorithm of random Fourier spectrum. This investigation is based on a comparative study of the mean spectrum and the standard spectrum of the random Fourier amplitude spectrum and the random coherence function between the simulated wind field and the objective wind field. A case study shows that the proposed random wind field simulation algorithm can reflect accurately the random characteristics of the given wind field.
