| Abstract | Ocean exploration is a challenge which provides knowledge of the environment and ecosystem. Autonomous underwater gliders are advantageous over conventional underwater vehicles. Performance can be evaluated by hydrodynamic characteristics. This paper presents a study of an hydrodynamics estimation for various underwater glider configurations. The designs of hull shape configuration of underwater gliders which is similar to torpedo shape are investigated. The hydrodynamics (drags) are estimated by using computational fluid dynamics. Reynolds-averaged Navier-Stokes equations with the SST model are used to solve this problem. The numerical studies are determined using the open-source software. The work shows results of hydrodynamics comparing a designed underwater glider with the Slocum glider. Performance of the gliders is also evaluated. |
