In this paper, the local wind field of a container terminal in Shanghai of China was simulated by CFD technique, and the corresponding spatial distribution of wind velocity, turbulence intensity and wind profile were investigated in detail.
The results of the simulation suggest that the local surrounding wind field of the investigated container terminal is remarkably influenced by the surrounding container ship and container piles.
