Keyword: liquid ammonia; leakage and diffusion; Gaussian puff model; MATLAB;
Abstract: The instantaneous leakage source gas diffusion concentration distribution model on the ground is established by using Gaussian puff model,and the atmospheric diffusion process about the ammonia is analyzied by using MATLAB to simulate the model.Finally the diffusion scope of danger which ammonia clouds form is obtained and the time and distance of diffusion which ammonia clouds dissipate without toxic need is obtained.The center of the ammonia clouds located at(1 068,0,0)when spread throughout 480 s.The highest concentration is lower than 30mg/m3.
