摘要
Abstract
Underwater gliders use the difference between gravity and buoyancy to obtain power.Underwater gliders usually have the advantages of low cost and high stealth performance.With the deeper exploration of the marine environment,underwater gliders are widely used in civil and military missions such as observing the marine environment.In this context,it is of great significance to accurately predict the gliding movement of underwater gliders and analyze the factors affecting gliding movements.The Computational Fluid Dynamics(CFD)method based on the RANS(Reynolds-Averaged Navier-Stokes)equation combined with the dynamic overlap method is applied to the direct simulation of a bionic underwater glider.The effects of the center of gravity displacement and net buoyancy of the underwater glider on the gliding motion during the navigation are studied.The trend of gliding speed ratio with the displacement of the center of gravity and net buoyancy is given and the roll and yaw moments experienced by the underwater glider are also analyzed.The results show that when the net buoyancy is 3%of the glider's gravity,the gliding speed ratio can reach higher than 4 by moving the center of gravity.This study can provide a certain reference for the design of underwater gliders.关键词
