ABSTRACT This paper investigates the flow field around the KRISO Very Large Crude Carrier (KVLCC2) model at different drift angle using the RANS method in combination with the Re-Normalization Group (RNG) and Shear Stress Transport (SST) turbulence models. The hydrodynamic forces and yaw moment acting on the KVLCC2 model are calculated under the different turbulence models and drift angles, and the numerical results are compared with previous experimental results. The accuracy of the numerical results is found to be acceptable, especially under the SST turbulence model. Three different mesh conditions are employed to perform the verification and validation based on the methodology and procedures suggested by ITTC. The surface pressure distribution, vorticity distribution, and surface flow features around the hull are observed and analysed. The maneuvering derivatives are calculated based on numerical results to create the mathematic model of ship maneuvering motions in the marine simulator and predict the ship maneuvering motions.

漂移条件下KVLCC2模型流场及机动导数的数值研究

摘要 本文使用 RANS 方法结合再归一化组 (RNG) 和剪切应力输运 (SST) 湍流模型研究了 KRISO 超大型原油运输船 (KVLCC2) 模型在不同漂移角下的流场。计算了不同湍流模型和漂移角下作用在KVLCC2模型上的水动力和偏航力矩，并将数值结果与前人的实验结果进行了比较。发现数值结果的准确性是可以接受的，特别是在 SST 湍流模型下。根据 ITTC 建议的方法和程序，采用三种不同的网格条件来执行验证和确认。观察和分析船体周围的表面压力分布、涡度分布和表面流动特征。
