Abstract

In this paper, results of numerical simulations for flow and diffusion fields around buildings are presented in order to demonstrate the great potential of the numerical method for predicting the outdoor environment in an urban area. The flow and diffusion fields around a single building, street blocks and a building complex which is actually under construction are simulated here. The k-ε{lunate} two-equation turbulence model and large eddy simulation are used for turbulence modeling. The accuracy of these simulations is examined by comparing the predicted results with wind-tunnel experiments. The animated graphics using various techniques of computer graphics are discussed.
