NUMERICAL STUDY OF TREE CANOPY IMPACT ON BUILDING LOCALWIND ENVIRONMENT

摘要

In this paper, a numerical model was proposed for simulation the tree canopy impact on building local wind environment. The large-eddy simulation was used for calculating the turbulent flow around the buildings. The proposed numerical model was coupled with the large-eddy simulation and provided an insight numerical study on pedestrian level wind environment around different high-rise buildings. The comfortable state of pedestrian level wind was predicted based on the numerical data. The method for improving wind environment of some areas was presented.
