基于BIM模型交互的风场模拟分析研究

Wind-Field-Simulation Analysis Based on BIM Technique

结合BIM与CFD风场模拟技术,建立基于BIM平台的Revit建筑模型,并通过模型交互衔接,导入Phoenics风场模拟环境,计算出各个风况的风场环境信息,以此评价室外风场的状况与Revit→Phoenics模型交互应用的可行性。研究结果表明:基于BIM模型交互应用的方法进行建筑场地通风模拟,能取得较好的效果,且通过模型的交互衔接可有效地在项目规划阶段利用BIM技术为设计师进行辅助参考及优化设计。

Combined with B/M and CFD wind field simulation technology, the paper established Revit architecture model based on BIM platform. Wind field information in various wind conditions were calculated by making the transformation from Revit to Phoenics, which was used to estimate the wind conditions and practicability of interactive application of Revit and Phoenics. The research results showed that it made effect in the BIM software interactive application to simulate site ventilation, which assisted the designers in optimizing the design in project planning stage.
