Numerical Calculation of Additional Mass for Undersea Vehicle
摘要
Abstract
Additional mass force on undersea vehicle is a fluid inertia force due to unsteady motion,which is difficult to obtain from experiment or numerical calculation.In this paper,an unsteady flow field calculation model of an undersea vehicle is presented in the moving coordinates system by making use of the 3D N-S equation and the k-epsilon turbulence model.The proposed model is verified by inertia force solutions of ellipsoid and circular cylinder models.Then,based on the present numerical method,the additional mass of an undersea vehicle is calculated.Simulation results show that the relative errors of the obtained additional mass are less than 10％.This numerical calculation method of additional mass may be helpful to the overall design and hydrodynamic calculation of an undersea vehicle.关键词
