Previously the effect of configuration of containers as well as wind angle of attack on the wind resistance of a container ship was studied by using simple blocks to represent the containers. However, in field observations, the authors testified large geometric deformations in statistically significant numbers of containers. Using ANSYS CFX, the outer side of the stacking configuration is modelled as a thin plate comprising several bays and tiers. Frictional resistance of the plate with corrugations and damages is compared to that of a flat plate. Moreover, using unsteady RANS with K-ω, SST turbulence model, a computer model of a single featured 3D unit is studied and compared with the simple block. In this case, viscous pressure drag is significant and results for simple block and real container are surprisingly different. In summary, differences in wind resistance between simple blocks and real containers are considerable and must be taken into account in future studies.

2D特色海洋集装箱和3D 40英尺单元的抗风性比较研究

以前,通过使用简单的块来表示集装箱,研究了集装箱配置以及风迎角对集装箱船抗风性的影响。但是,在实地观察中,作者证明了具有统计学意义的大量容器中的大几何变形。使用ANSYS CFX,堆叠配置的外侧被建模为一个薄板,包括多个托架和层。将具有波纹和损坏的板的摩擦阻力与平板的摩擦阻力进行比较。此外,使用具有K-ω的非定常RANS,SST湍流模型,研究了单一特征3D单元的计算机模型并将其与简单模块进行了比较。在这种情况下,粘性压力阻力很明显,简单的块状容器和实际容器的结果令人惊讶地不同。综上所述,
