摘　　要：针对大机动极限工况下水下航行体流动分离带来的机动性不足问题,本文以Suboff标模为研究对象,采用大涡模拟数值计算方法开展大机动工况下水下航行体的流体动力性能评估,并完成水下航行体尾部及舵面流动分离涡旋结构的精细捕捉。本文研究成果可为后续极限机动工况下水下航行体流动控制提供技术支撑。In response to the issue of insufficient maneuverability caused by flow separation of UUV under extreme maneuverability conditions,this paper takes the Suboff as the research model,using the Large Eddy Simulation method to evaluate the fluid dynamics of UUV under high maneuverability conditions.The results obtained in current study can provide technical support for the flow control of underwater vehicles under extreme maneuvering conditions in the future.
