Abstract

The turbulent flow and the pollutant dispersion in organized cubic structures simulating an idealized building arrangement in a city is numerically investigated. The basic building arrangement under investigation is the experimental arrangement reported by Uehara et al (2000); it consists of an in line arrangement of cubic blocks having upwind a number of low rise square blocks which act as roughness elements for creating turbulent flow. The purpose of the investigation is to gain physical knowledge on the structure of the three dimensional flow and the pollutant dispersion mechanism, to compare with published two dimensional simulations and mainly to investigate the unsteady character of the flow field and its time scale characteristics.
