| 摘 要： | 通过求解RANS方程,选取RNGk-ε湍流模型,在模型尺度下对KVLCC2船-舵系统处于不同漂角时的斜航黏性流场进行数值模拟.首先采用3套网格进行网格收敛性分析,然后通过计算结果与试验数据比较,验证数值计算方法的可靠性.在此基础上,计算了舵角为零时不同漂角下以及不同舵角、不同漂角下作用在船-舵系统上的横向力和转首力矩,并对计算结果进行了分析.

| Abstract: | Abstract： By solving the RANS equations in conjunction with a RNG k-ε turbulence model, numerical simulation of the viscous flow around a KVLCC2 model appended with a rudder moving at different drift angles was conducted. The grid convergence study was performed using three sets of grid, and the computed and measured results were compared to show the reliability of the numerical method. Besides, the lateral force and yaw moment acting on the hull-rudder system moving at different drift angle, with and without rudder angle were calculated, and the numerical results were analyzed. |
