摘要
建筑形体设计对建筑室内外风环境有很重要影响,而架空设计是改善室外风环境的手段之一。将计算流体力学(CFD)模拟与建筑设计相结合,能够更好地为建筑设计提供依据,优化建筑设计方案。通过CFD模拟,探究西交利物浦大学中心楼在有无架空及不同架空高度对建筑周边人行高度风环境的影响。结果表明,建筑架空设计对建筑周边高度1.5 m处的风环境有良好的提升作用。对于案例和类似高度的建筑而言,架空高度在2.4~3.0 m时,架空设计能够提升建筑迎风区1.5 m人行高度的风速大小,当架空设计高度在3.0 m以上时,架空设计对建筑迎风区1.5 m高度处风速大小影响较小。
Architectural form design is crucial to building indoor and outdoor natural ventilation,and elevated building design is one of the methods for improving the outdoor wind environment.Through integrating computational fluid dynamics(CFD)simulation with architectural design,an informed design for architectural design is provided for better architectural design schemes.CFD simulation was used to explore the impacts of elevated heights on the XJTLU Central Building’s wind environment at the pedestrian height around the building.Results show that the elevated design of the building has a good effect on improving the wind environment at the pedestrian height of 1.5 m around the building.For this study case and similar height buildings,the elevated design can increase the wind speed of the 1.5 m pedestrian height in the windward area of the building when the elevated height is 2.4~3.0 m.When the elevated design height is above 3.0 m,the elevated design has little impact on the 1.5 m height wind speed at the windward area of the building.
