摘要
为保证舒适性和良好的自然通风,生态建筑对室外风环境,特别是行人高度的风环境有着明确的要求.为此,在生态建筑的规划和设计时,有必要借助风洞试验或数值模拟方法对规划和设计方案进行检验和修正.本文采用有限体积法和SIMPLE算法,对天津中心生态城中首个绿色建筑的设计模型周边行人高度风环境进行了数值模拟分析,并根据数值模拟结果对设计方案提出了参考建议.
In order to guarantee comfort and good natural ventilation,an ecological building demands the outdoor wind environment,especially the pedestrian level wind environment to meet the related requirements.So when planning and designing an ecological building,it is necessary to use wind tunnel trials or numerical simulation methods to test and modify the program.Using finite volume method and SIMPLE algorithm,this paper carries out the numerical simulation analysis on the pedestrian level wind environment around the design model of the first green building in the Sino-Singapore Tianjin Eco-city,accordingly some suggestions are put forward for the design scheme.
