Optimization of Tree Canopy Model for CFD Prediction of Wind Environment at Pedestrian Level

ABSTRACT: The canopy model for reproducing the aerodynamic effects of trees based on k-e model was optimized for the CFD prediction of wind environment at pedestrian level. After reviewing the previous researches on modeling canopy flows, two types of canopy models were selected. In addition, the model coefficients adopted in the extra term added to the transport equation of turbulence energy dissipation rate, e were optimized by comparing numerical results with field measurements.
