Other Abstract

It is necessary to predict the hydrodynamic performance of AUV (Autonomous Underwater Vehicle) underwater docking accurately to improve the success. A method of multi-block hybrid grids combined with a dynamic layer method and UDF (User Defined Function) was presented, which was applied to the physics-based simulation of AUV underwater docking by self-propulsion with a discretized propeller. In this method, subdomain-moving substitutes for boundary-moving used in traditional dynamic mesh, which could improve the calculation efficiency. After the numerical validation of the velocity history of AUV self-propulsion against the experimental results, the hydrodynamic performance and flow field of AUV underwater docking were investigated. The results demonstrate that the time of AUV underwater docking from stationary by a constant rotating propeller of 300 RPM (Revolutions Per Minute) is about 16s. The end velocity reaches 0.75m/s, which meets the demand for collision. The effect from the dock on AUV locates on the neck point B. There is a drag on AUV before B, followed a suction after B. The increment of resistance is small with a value of 2.4%. AUV can reach the dock.
