Abstract

A numerical simulation analysis based on Computational Fluid Dynamics (CFD) was used to study the leakage of ammonia storage tank in the Beijing Winter Olympics snowmobile sled stadium. The leak location and leak flow rate were varied to investigate their effects on the dispersion profile. Different positions of leakage points of ammonia storage tank led to different dangerous regions. With the same flow rate, the dangerous area caused by the leakage on the left side of the liquid ammonia storage tank is the largest. However, the leakage from the top of the storage tank has almost no effect on the ammonia concentration near the ground. When the bottom leaks, the high concentration of ammonia gas is mainly gather near the ground. The work in this paper can provide technical support for improving the safety of ammonia leakage accident.
