Abstract

Hydrodynamic coefficients for an autonomous underwater vehicle (AUV) are obtained by simulating the maneuver tests in computational fluid dynamic (CFD) media. The simulations are performed for different length to diameter ratios by STAR-CCM+ software. Also the effects of different hydroplanes as a hull appendage is investigated. Hydrodynamic forces and moment are computed and by using suitable curve fitting linear and NONLINEAR HYDRODYNAMIC COEFFICIENTS are calculated. The results show that by increasing the length to diameter ratio the higher hydrodynamic coefficients can be obtained. The comparison of simulated results with the available experimental data shows a very good agreement among them.
