关键词Underwater Vehicles Hydrodynamics Computational Fluid Dynamics Momentum Sources
摘要An added momentum sources-based method is proposed in this paper to compute hydrodynamic coefficients of an underwater vehicle. It is assumed that the vehicle is at rest. Added momentum sources are introduced to account for the effects of the Coriolis acceleration and the acceleration of entrainment because the frame of reference is attached on the underwater vehicle. Compared with a moving boundary method, the method presented need not to reconstruct meshes, and can simulate wind/water tunnel tests and rotating arm tank tests at less efforts. The computational results for a flat type of autonomous underwater vehicle, named SMAL01, prove the validity of the method, and show that the hydrodynamic coefficients from numerical calculations agree well with those from scale model tests.
