摘　　要：基于重叠网格技术,采用URANS粘性数值模拟方法,对标准船模KVLCC2裸船体的航向稳定性进行了数值预报。基于STAR-CCM+平台,采用重叠网格技术和切割体网格,根据SIMMAN2014提供的标准算例,对KVLCC2进行了斜航运动和纯艏摇运动的数值模拟,得到了横向力和转首力矩的历时曲线,并根据操纵性数学模型推倒出水动力导数,并计算稳定性衡准数,所有计算结果同模型试验数据吻合较好,验证了采用当前处理方法预报航向稳定性的可靠性。Based on the Over-setgrid and URANS viscous numerical simulation method,the directional stability of the standard ship model KVLCC2 in bare hull condition is predicted.The numerical computations in this study were performed on the STAR-CCM+,using the over-setgrid and trimmed mesh.According to the SIMMAN2014,the KVLCC2 in oblique motion and pure yaw motion were numerical simulated,the time histories of lat-eral force and yawing moment were obtained.According to the maneuvering mathematical model,the hydrodynamic derivatives were obtained and course stability index was calculated.All numerical results were in good agreement with model test data,which indicated that the reliability of the current approach for predicting directional stability.
