Abstract
This paper presents the initial development towards the modelling of a free running
simulation to examine the manoeuvring performance of self-propelled underwater vehicles.
The simulation consists of a coupled Computational Fluid Dynamics (CFD) and Rigid Body
Dynamics (RBD) model that enables the prediction of the vehicle’s hydrodynamic
characteristics and trajectory. It uses a Moving Domain Technique (MDT) that overcomes
grid deformation and boundary limitation issues.
The CFD model was validated against Experimental Fluid Dynamics (EFD) data for a prolate
spheroid and a generic bare hull (SUBOFF), with the coupled model verified for the two hulls
by undergoing straight line manoeuvres. An actuator disk propeller was then added to a fully
appended SUBOFF model to simulate a 1-DOF self-propelled free running vehicle.
Future work is in progress to expand the capability of the model for 6-DOF manoeuvring
simulations. The model is intended as a cost effective tool to complement free running
experimental work, hence reducing the reliance on specialised experimental equipment and
providing a tool that can predict manoeuvring conditions beyond experimental limitations.
