Abstract
The consequences of emergency coal gas leakage from storage tanks to the air is terrible, so the diffusion pattern of coal gas (such as light gas) must be cognized to avoid the harm to on-site workers. This paper simulates the leakage and diffusing process of coal gas by establishing simplified two-dimensional plane model, and applied LES turbulence model to get the regulations of how CO concentration changes with time and space. The results of the simulation show that, a) Initially, the distribution of CO concentration near the leaking spot is more concentrated during the leaking process; b) After the leaking process, the concentration of CO reduces smoothly and gently rather than decreases rapidly under natural ventilation conditions. The results revealed in this paper are of great significance to the alarm and responding scenario of emergency gas leak.
