Other Abstract

The cruising velocity of autonomous underwater vehicle (AUV) plays an important role on evaluation of the thrust system performance and cruising endurance. This paper presented a physics-based numerical method for prediction of AUV’s cruising velocity. The full model of AUV appended propeller and rudder was built. A multi-block hybrid dynamic grid method was used to mesh the domain and re-meshing. User defined functions (UDFs) were programmed. Six degree of freedom (6DOF) and unsteady Reynolds averaged Navier-Stokes (URANS) were solved to transfer forces and velocities between AUV and propeller. Thus, the free motion of AUV pushed by the rotating propeller from stationary to uniform velocity was simulated. The numerical results showed that the rotating speed was 570 r/min at the cruising velocity of 1.5m/s. The tip vortexes were produced in self-propulsion motion. The strength of tip vortexes and propeller thrust decreased as AUV velocity increased. The simulation investigated the unsteady flow field among the hull, propeller and rudders in detail, which is helpful to conduct a precise maneuvering prediction of AUV in complex environment.
