Due to the difficulties of a field experiment for atmospheric environmental assessments or efficient utilization of wind energy, the analysis using computational fluid dynamics (CFD) is highly expected. In our laboratory, a CFD code has been developed for the prediction of airflows over real complex terrain. And the CFD code has high accuracy to predict wind field in complex terrain in the past work. However, it has not been applied to gas diffusion field for atmospheric environmental assessment yet. In this study, numerical simulations of gas diffusion over an isolated hill and real complex terrain were carried out as the first step to establish a prediction method. The numerical results agree with wind tunnel experimental results and field data.
