Analysis of resistance characteristics of underwater vehicles based on FLUENT

水动力参数是水下航行器操纵性设计的重要参数。针对一款水下航行器,通过UG建立了水下航行器的三维模型,利用计算流体力学(CFD)的方法对两种状态下的水下航行器的阻力特性进行了有限元分析,得到了不同状态下的水下航行器阻力性能参数,并对这些参数进行比较分析,实验对比表明,该方法对无人水下航行器的阻力特性的预测精度较高,且对流场的显示更加详细、直观,为后续的外形设计提供重要的参考依据。

Hydrodynamic parameters are important parameters for the maneuverability design of underwater vehicles.A three-dimensional model of an underwater vehicle was established through UG,and the resistance characteristics of the underwater vehicle under two different states were analyzed by using computational fluid dynamics(CFD).The resistance performance parameters of the underwater vehicle under different states were obtained and compared.The experiment and comparison showed that the method had high prediction accuracy for the resistance characteristics of unmanned underwater vehicles,and the display of the flow field was more detailed and intuitive,providing important reference for subsequent shape design.
