摘　　要：结合参数化建模、数字建造、计算机流体动力学模拟和风洞实验建立实景三维建筑风场可视化分析方法,通过实验验证分析,对比研究不同曲面形态建筑的风场。研究显示,所建立的方法可对建筑风场的相关特性进行高效地可视化和量化分析;曲面形态建筑周围的通风效果较优,相对长方体形态建筑风速较高;曲面形态建筑的凸面朝向迎风面时,建筑对气流的阻碍作用小于凹面处于迎风面时的情形,将凸面朝向迎风面有助于促进建筑周围环境的通风。该研究方法提供高效准确的建筑物风场分析路径,可作为实景三维平台在建筑设计与工程应用的分析手段,为城市的可持续策略、微气候研究和精细化治理提供有价值的信息。Building morphology can affect its surrounding wind field,and building wind field analysis is indispensable for urban microclimate research and sustainable design,and provides a basis for urban fine-governance in 3D real-scene applications.In this study,we establish a building wind field visualization scheme through parametric modeling and computer fluid dynamics(CFD)simulation,and conduct a validation study through designed wind tunnel experiments to compare and analyze the wind field of buildings with different curved surface morphologies.The study shows that the CFD method can better visualize and quantify the relevant characteristics of the building wind field;the wind speed around the curved building is higher than that around the rectangular building,and the ventilation effect is better;the obstruction effect of the building is smaller when the convex side is facing the windward side than when the concave side is on the windward side.Orienting the convex side of the building towards the windward side helps to promote the ventilation of the building surroundings.This wind field visualization research method can provide efficient and accurate wind field analysis,which can provide valuable decision-making information for urban real-life architectural projects,and can be used as an analytical tool for the application of the real-life 3D platform in architectural design and site selection.
