| Abstract: | The H2S leakage accident is simulated by applying computational fluid dynamics(CFD) theory.The movement characteristics of H2S and its concentration distribution regularity in the diffusion process under different wind speeds and wind directions are obtained when H2S leaks for 10 minutes.Based on the characteristics of the concentration distribution and change,the paper analyzes the influence law of wind speed and buildings on the diffusion of H2S.The results provide certain guidance for recognition of heavy gas diffusion law,accident prevention and evacuation. |
