摘要
台风风特性的现场实测与计算流体力学(computational fluid dynamics, CFD)数值模拟是研究台风作用下结构风效应和城市地形风场特性的主要方法。采用综述形式,对当前台风风场特性现场实测与数值模拟研究的基本方法、主要内容、待解决问题及未来发展趋势进行了归纳及总结。现场实测台风数据为台风风特性的研究提供有力的科学根据,在数值模拟软件中对台风风场进行模拟极大方便了对台风风特性的研究。目前,台风实测数据还十分有限,台风非平稳性和地域性差异等因素导致难以用数值模拟的方式准确描述城市地形风场环境。未来,需以现场实测和数值模拟相结合的方式,总结风场特性,对城市地形风场建立适配的台风数学分析模型,得到合适的结构设计风参数选值方法。
Field measurements and computational fluid dynamics(CFD)numerical simulations of typhoon wind properties are the main methods to study the structural wind effects and urban terrain wind field properties under typhoon action.The basic methods,main contents,problems to be solved and future development trends of current field measurements and numerical simulations of typhoon wind properties were summarized in the form of a review.The field measurements of typhoon data provide a strong scientific basis for the study of typhoon wind characteristics,and the simulation of typhoon wind field in numerical simulation software greatly facilitates the study of typhoon wind characteristics.At present,the measured typhoon data are still very limited,and the non-smoothness and geographical differences of typhoons make it difficult to accurately describe the wind field environment in urban terrain by numerical simulation.In the future,a combination of field measurements and numerical simulations is needed to summarize the wind field characteristics,to establish an adapted typhoon mathematical analysis model for urban terrain wind field,and to obtain a suitable method for selecting the wind parameters for structural design.
