Numerical Simulation of Hydrodynamic Co-efficient of Underwater Gliders

The numerical simulation of the vertical and longitudinal hydrodynamic coefficient test of the three-dimensional rotary ellipsoid was carried out by using the three-dimensional Navier-Stokes equation, and the numerical simulation of the transverse and bow swing test of the SUBOFF model submarine was further carried out on this basis. The motion forms of the underwater glider hanging, longitudinal, transverse and bow rocking experiments are analyzed, and the corresponding mathematical equations are derived, and the numerical prediction simulation of the hydrodynamic coefficient of the underwater glider is carried out. The results show that the calculation results of the numerical simulation method of hydraulic coefficient of underwater gliders developed in this
