Based on CFD-Fluent software platform, leakage diffusion of ammonia storage tank area is simulated, Main study on wind speed and leakage direction of influence on ammonia leakage diffusion process as well as the range of severe and moderate risk zone. The results show that the wind speed affected gas parameters such as diffusion area, jet distance, and concentration, different leakage direction caused different degree of status, and leakage against the wind is the most unsafe condition. Through the numerical simulation of ammonia leakage diffusion process, correctly judging the behaviour of leak occurrence, development and influence scope, provide scientific guidance for delimiting warning zone after the accident.
