Abstract:
Because of the complex buildings, the wind flow and the pollution diffusion will be affected in the microscale such as urban neighborhood or the site of facility, the straight Gaussian plume model will not be available. Based on the Reynolds-Averaged Naiver-Stokes(RANS) method which was used to calculate the wind field with the Lagrange particle random walking model, the radioactive pollution diffusion model and microscale radiation environmental impact assessment software system were developed. This system can be used in the factory or city streets and other similar conditions for simulating radioactive pollutants diffusion behavior. The development of the system will provide technical tools for the microscale radiation environmental impact assessment in the future.
