【 摘 要 】

The discharge of VOCs in the port area is harmful to the environment and the human body. Therefore, this paper aims at transient leakage of VOCs in cargo port area. The diffusion process was simulated with Fluent software, and this paper considered the impact of changes in wind speed on the diffusion concentration distribution. The results show that when the wind speed is higher, the earlier the initial concentration appears, the greater the concentration peak is, and the longer the VOCs spread. The increase of the wind speed is conducive to the diffusion of VOCs.
