In this paper, the numerical simulation method is used to study the gas diffusion in a limited space under the scene of poisonous gas attack or leakage. Based on the STAR-CCM + software, the toxic gas diffusion process in a limited enclosed space under specific flow field conditions was simulated and analyzed, and the effects of different wind speeds on the diffusion law and concentration field distribution were studied.
