摘　　要：水下航行器由于其功能多样性的需求,发展形成了各式各样的附体结构,这些附体结构在满足特定功能的同时可能会改变航行器的外流场特性。本文针对某水下航行器,采用数值计算方法分析附体结构对于航行器的阻力影响,在此基础上设计几种导流型附体结构,获得各个附体结构的减阻效果,其中最优方案阻力降低达19.7%,通过可视化手段分析其流场的压力、速度以及三维涡结构分布。通过上述研究工作,明确了水下航行器附体结构外流场特性,为航行器附体结构的设计与优化提供了有益参考。Underwater vehicles have developed various appendage structures due to their functional diversity requirements.These appendages may change the characteristics of external flow field while meeting specific functions.For an underwater vehicle,this paper uses numerical calculation methods to analyze the influence of appendage structure on the resistance of the underwater vehicle.On this basis,several kinds of diversion appendage structures are designed,and the effects on drag reduction of each model are obtained.The drag of the optimal solution can be reduced by 19.7%.The distribution of pressure,velocity and three-dimensional vortex structure of the flow field are analyzed in detail through visualization methods.Through the above research work,the characteristics of the external flow field of the appendage structure of underwater vehicle are clarified,which provides a useful reference for the design and optimization of the appendage structure of underwater vehicle.
