摘要：
A wind tunnel simulation of airflow and pollutant diffusion has been conducted for Mt. Tsukuba, a rather isolated mountain. The wind tunnel simulation was carried out in the Thermally Stratified Wind Tunnel of the National Research Institute for Pollution and Resources. The scale of the topographic model was 1/7500 for the horizontal and 1/5000 for the vertical. A nocturnal inversion was simulated in the wind tunnel by heating the airflow to 40-degrees-C and chilling the floor of the test section at 10-degrees-C. The wind tunnel free stream speed was 0.5 m s-1. The airflow was found to be satisfactorily simulated in the wind tunnel. The upstream flow stagnation, the dividing streamline and the wake in the lee of the mountain were reproduced.
