Abstract

The aim of this study is to develop a simulation method for predicting the wind environment and turbulent diffusion process, whichare affected by moving automobiles within the real situation of urban street canyon. In this study, a simulation method to reproduce the aerodynamic effects generated from the moving automobiles based on the methodology of canopy models, namely 'Vehicle Canopy Model', was developed. Furthermore, a series of wind tunnel measurements of flow over car-shaped roughness elements and the dragforces caused by the roughness with different configurations and densities were carried out. By comparing the results of CFD predictions of the developed 'Vehicle Canopy Model' with experimental data, the accuracy of the developed model was examined.
