摘要
通过对脉动风场模拟技术近20年来国内外研究成果的总结,阐述了脉动风场模拟研究的发展历程。首先简要介绍了近地风场的特性和脉动风场模拟技术的研究现状,然后从脉动风场模拟技术的研究方法出发,分别介绍了谐波合成法、线性滤波法和小波方法在风场模拟技术中的研究发展现状和所面临的问题,最后对风场模拟技术的未来趋势进行了展望。
According to the fluctuating wind field simulation technology at home and abroad in the past 20 years, a summary of research results expatiates the development process of the fluctuation wind filed simulation technology. First of all we give a briefing on the characteristics of boundary layer wind and the status quo of the fluctuating wind field simulation technology. And then, based on the research of the simulation technology of fluctuation wind field, we introduce the current situation and problems of harmonic wave superimposing method, linear filtering method and wavelet method. Finally, we prospect the future of the research.
