A
three dimensional study was carried out to investigate the effect of
the Reynolds number on the drag forces acting on an AUV prototype. The
Shear Stress Transport based K-Omega turbulence model was used
in this study. The Figures in the left column show the underwater vehicule
configuration and the grid used around it. The Figures in the right
column show the mean horizontal velocity distribution around the AUV
moving at 6 m/s and the profile of the drag forces versus AUV velocities.
