Abstract

Wind tunnel test using rigid model and CFD numerical simulation has been carried out to investigate the wind load distribution and the wind environment of large ferry terminal. Wind load distributions on the roof of the ferry terminal drawn from numerical simulation agree with the results drawn from wind tunnel test, which shows that the provided numerical model can simulate the airflow around the ferry terminal. Analysis results show that, the layout of buildings in the ferry terminal affects the wind load on the roof. With decreasing of the height of the ancillary buildings under the roof, the separation of airflow at the edge of the roof is relieved and wind load acted on the roof is decreased. Analysis about the wind environment shows that, the interference effect caused by the buildings is the main reason for wind speed acceleration, and the problem of wind environment around the ferry terminal is prominent.
