N2 - In this paper, an AUV pressure drag simulations with different velocities are presented. The AUV’s main hull is spherical but its instrumental components extend out of the hull, and interfere with the flow. A pressure drag coefficient of a sphere was simulated to decide the used turbulence model (SST k-ω), by comparing simulation results to those found in literature. Then, simulations were done with different velocities to understand the behaviour of the AUV drag coefficient. These results can be used to improve the control system of the AUV and are an important factor in the AUV energy consumption.
