Large-Eddy Simulation を用いた単体建物モデル周辺歩行者高さにおけるピーク風速統計量の評価と不確かさ分析

This study examines the peak wind speed statistics and their uncertainty at the pedestrian level around an isolated building model using Large-Eddy Simulation (LES). Understanding pedestrian-level wind conditions is crucial for building design focused on comfort and safety. Traditional methods, often limited by the inability to directly assess peak speeds through wind tunnel experiments or computational fluid dynamics, rely on lower-order statistical measures combined with gust and peak factors. Our approach allows for a more direct and reliable estimation of these wind statistics, providing insights into the complexities of building-induced winds and their impact on pedestrian-level environments.
