| Abstract: | The characters of some numerical models which describe discharging dispersion process of flammable or toxic gases have been analyzed. The models include Gaussian plume/puff model, Gaussian plume trajectory model, BM model, Sutton model and FEM3 model. Gaussian plume/puff and Gaussian plume trajectory models used abroad have been introduced emphatically. Aiming at the complication of the dispersion process,such as weather conditions and landform situation which influence the diffusion process of flammable or toxic gases have been analyzed in detail, and some countermeasures have been put forward to ascertain some uncertain parameters. |
| Keywords: | flammable or toxic gases discharging dispersion model simulation |
