A numerical simulation method has been developed to predict atmospheric flow and stack gas diffusion under the buildings and complex terrain conditions. The turbulence closure technique was used for flow calculation, some calculation grids on the ground within a plant area were treated as buildings under the terrain following coordinate, and stack gas diffusion was predicted using the Lagrangian particle model. The numerical model have been applied for the flow and stack gas diffusion around cubical building and two dimensional ridge terrain conditions in this report. Then, the calculated flow and stack gas diffusion results were compared with those obtained by wind tunnel experiments, and the features of flow and tracer gas diffusion, such as the increment of turbulent kinetic energy and plume spreads of stack gas behind the buildings and terrain, were reproduced by both calculations and wind tunnel experiments.
