Research Abstract

This research pays attention to street canyons as the fundamental unit of thermal and wind environment in built-up area. By wind tunnel experiment and field observation in actual buildings, the basic structure of pollutant dispersion was clarified. Based on the database obtained by this study, important information for highly precise and practical turbulent modeling for advection and turbulent diffusion were obtained for developing the prediction and evaluation methods for the pollutant transport using CFD.
