Hydrodynamic performance of a flapping wing based AUV-a numerical study

摘要：

　　A conceptual design of bio-mimetic autonomous underwater vehicle (AUV) based on parallel twin flapping wings is proposed, and its hydrodynamic performance at Re=200 are investigated by numerically solving the incompressible viscous Navier-Stokes equations coupled with the immersed boundary method.Compared to a single flapping wing, the existence of the AUV body helps to reduce the drag forces or enhance the thrust force that acting on the twin flapping wings.The AUV body inhibits the tip vortices on the near-body side of the flapping wings, resulting the asymmetric vortex streets in the wakes and the circular vortex ring is no longer observed in the wakes.The correlations of the flow structures, the hydrodynamic interactions and the hydrodynamic performance of the AUV are discussed.
