Other AbstractFor the problem of numerical calculation hydrodynamics of unmanned underwater vehicles (UUVs), this paper presents a method based on static meshes and added momentum sources in a body-fixed coordinate frame. First, by deriving the N-S equations in a body-fixed frame, it is proved that added momentum methods can be used to simulate steady motion and unsteady motion of UUVs on the basis of static meshes. To validate the feasibility of the method for viscous hydrodynamics calculation, the SUBOFF standard submarine model and a 4500 m AUV model are used and compared with tank test results. And, to validate the feasibility of the method for inertial hydrodynamics calculation, the added masses of an ellipsoid are computed and compared with theorical values. The comparison showes that the proposed method can meet the hydrodynamic force computing well, and the method can avoid those problems such as long time comsuming, bad convergency, which usually caused by dynamic mesh methods or overset mesh methods.
