Abstract :
Research on the neutral gas diffusion simulation, improved the Gaussian plume model which simulate under continuous leakage status. Add the terrain factor to the model; calculate with digital elevation model (DEM) in order to verify the idea. Using geographic information system (GIS) control technology developed chemical gas leakage simulate system, take the ammonia diffusion for instance, dynamic simulate its diffusion process, demonstrate the improved model is correct, make the Gaussian plume adapted to the gas diffusion simulation under the urban areas, and also improve the calculation accuracy of the model, provide more reliable decision support for urban emergency response.
