Other Abstract

It is necessary to predict accurately the maneuverability of autonomous underwater vehicle (AUV)diving by self-propulsion to improve its safety and stability. A method was presented to predict the vehicle’s forces and flow details in real time during forced diving motion which built a full appended model, simulated the propeller's rotating motion, coupled with user defined function(UDF)and solved the Reynolds-averaged Navier-Stokes (RANS)equations.This method can improve the accuracy and computation efficiency of dynamic mesh method by using multi-block mesh with moving zone method. The numerical method was validated by comparison between computational and experimental results of AUV's velocity in AUV self-propulsion test. The numerical results of AUV forced diving by self-propulsion showed that:at the initial time,the AUV had a large acceleration resulting in a large resistance. When pitch changed, the vertical force oscillated. The wake of propeller twisted and the thrust of propeller varied. In the steady diving, the thrust and resistance became steady.
