潜艇大舵角状态下的水动力性能与潜艇大机动状态下的操纵性能之间存在密切联系，基于STAR-CCM+中的RANS与DES求解器开展SUBOFF潜艇斜航工况下操舵水动力及绕流场数值预报研究，分析不同数值方法获得的潜艇纵向力、横向力、转首力矩以及潜艇绕流场随舵角的变化规律，以及相应的泄出涡系结构、流线分布和压力分布，揭示了潜艇操纵工况下水动力性能与绕流场间的内在联系。研究表明，DES方法在潜艇操纵工况下的水动力性能预报及流场细节捕捉方面优势明显，验证了其在研究潜艇大机动状态操纵性能方面的有效性。
Considering the close relationship between the hydrodynamic performance of the submarine with a larger rudder angle and its tight maneuverability, the numerical investigation of the steering hydrodynamics and flow fields of the SUBOFF submarine model under the oblique towing condition was performed by using the RANS and DES solvers in STAR-CCM+. The variation of the longitudinal force, lateral force, and yaw moment with the rudder angle, as well as the corresponding vortex system structure, streamline distribution and pressure distribution were analyzed. The internal relationship between the submarine hydrodynamic performance and the flow field was revealed. The study indicates that the DES method has obvious advantages in predicting the hydrodynamic performance and capturing the flow field details for the submarine under the maneuvering condition, which is proved to be an effective numerical method to study the tight maneuverability of the submarine.
