Abstract
When an Autonomous Underwater Vehicle (AUV) operates close to a submarine, interaction with the
flow and pressure fields of the submarine can adversely affect the motion of the AUV. These interactions
can result in uncontrollable motions of the AUV, which in extreme cases can lead to mission failure due
to collision with the submarine or the inability of the AUV to maintain the desired trajectory. This paper
outlines the steady-state interaction forces and moments acting on the AUV at different fixed speeds and
relative positions to the submarine, with an aim to identify the regions where adverse effects due to
interaction are minimal. The results presented in this paper are from a series of model scale and full scale
Computational Fluid Dynamics (CFD) simulations on axisymmetric AUV and submarine models at
diameter ratios between the two vehicles models of 2.239, 5.723 and 14.634. Validation was carried out
for the lower diameter ratio at model scale using captive model experiments. Results show that the
adverse effects of the interaction forces and moments were minimal when the AUV's centre of buoyancy
is around amidships of the submarine, providing a relatively safe operating path for the AUV.
