Research of Wind Resistance and Flow Field of Container Ship

Abstract

In order to study the super large container ship characteristics of the wind resistance coefficient and the air flow field in the different angle of attack, wind tunnel test based on the 14000 containers ship is carried out on the state of the design draft. The wind resistance coefficient of superstructure is obtained through test. The CFD (Computational Fluid Dynamics) technology is introduced to simulate the wind resistance and yaw moment of the model. The numerical results are basically in agreement with the experimental data. The results indicates that with the increase of the wind direction angle, the longitudinal wind resistance coefficient curve shows a “sine curve” rule and exists opposite resistance extremums, whereas the lateral wind resistance coefficient curve presents a parabolic change rule. Numerical simulation method is proved has high accuracy for wind resistance prediction of container ship. The size of wind load on the ship is related to the form and size of the wake region.
