摘　　要：以典型护卫舰简化模型SFS为研究对象,研究适用于复杂船型的网格划分方法.对比了结构、非结构和混合网格三种网格形式下的流场计算结果,研究表明:网格形式并不会显著影响计算结果,且混合网格在适用性方面优于结构化网格,网格数量控制方面优于非结构化网格.为验证混合网格精度,以CVN-73(乔治·华盛顿号)为验证对象划分混合网格进行数值计算,获得了与风洞试验具有较高符合度的仿真结果,证明混合网格针对复杂船型的CFD仿真计算更具优势,验证了混合网格的适用性.A proper meshing generation method for complex ship was studied ,and a simplified frigate shape （SFS） was as the research object .Three types of structured ,unstructured and hybrid mesh were calculated and compared .Research results show that the mesh type does not significantly affect the results ,and the hybrid mesh has a better applicability than the structured mesh and less mesh than the unstructured mesh .To verify the accuracy of the hybrid mesh ,CVN‐73（USS George Wash‐ington） with hybrid mesh was calculated and the simulation result was in good agreement with the wind tunnel test ,which verifies that the hybrid mesh has advantages in complex ship simulation .
