This paper deals with the analysis of confined water effects on the manoeuvring capabilities of a submarine. The analysis is carried out by using numerical simulations based on the Reynolds Averaged Navier Stokes equations of a submarine moving with constant speed on a straight path at zero and nonzero drift/pitch angles, in open water, close to the bottom, and close to the free-surface conditions. The features of the flow around the submarine are described in terms of velocity and pressure fields; the computed force and moment coefficients are presented and compared with experimental data collected at INSEAN.

Abstract
This paper deals with the analysis of confined water effects on the manoeuvring capabilities of a submarine. The analysis is carried out by using numerical simulations based on the Reynolds Averaged Navier Stokes equations of a submarine moving with constant speed on a straight path at zero and nonzero drift/pitch angles, in open water, close to the bottom, and close to the free-surface conditions. The features of the flow around the submarine are described in terms of velocity and pressure fields; the computed force and moment coefficients are presented and compared with experimental data collected at INSEAN.
