摘要
城市风热环境研究对于城市可持续发展、居民健康和气候变化适应性都具有重要意义.随着高性能计算能力的不断提升和数值模拟方法的改进,计算流体力学(Computational Fluid Dynamics,CFD)已经广泛应用于城市风热环境预测.本文概括性地总结了城市风热环境实验研究和CFD研究的进展,包括典型的实验研究方法、CFD数值模型、模型验证等,并重点从建筑形态布局、植被、水体以及冷性材料 4 个方面对CFD应用研究成果进行归纳总结,最后从多季节、多尺度、精细化模拟以及多因素耦合等角度对未来城市风热环境CFD模拟研究进行了展望,并提出了参考建议.
Abstract
Investigating urban wind and thermal environments is of great significance for the sustainable development of urban,residents'health,and urban suitability addressing climate change.With the continuous advancement of high-performance computational capacity and improvement of numerical methodologies,Computational Fluid Dynamics(CFD)has been widely utilized to numerically simulate urban wind and thermal environments.This study aims to summarize the research processes of CFD simulations in China on urban wind and thermal environments in the past two decades,including the typical experimental research methods,CFD numerical models,and model validation techniques as well as key findings,specifically addressing the impacts of architectural geometry and configuration,vegetation,water bodies,and cool materials.Finally,this study concludes by providing prospects for the future CFD simulation of urban wind and thermal environments,focusing on multiple seasons,multi-scale analysis,high-resolution simulation,and the coupling of various influencing factors,providing reference for future researches.
