Abstract

A numerical methodology has been developed to accurately simulate the flow around a towed hull. A mesh structure has been developed that efficiently captures the free surface wave pattern, whilst allowing for easy implementation of a propeller model in the future. The numerical wave pattern generated has been validated against experimental data showing good correlation.
An assessment of the aero and hydrodynamic components of drag highlighted the need for more detailed information about the ‘above water’ experimental set up from towing tank experiments, if accurate validation is to be achieved.
The impact of two different turbulence models on the components of resistance has been evaluated, concluding that the Baseline (BSL) Reynolds stress model provided the best comparison to experimental data. It is therefore now envisaged that this numerical methodology can be used to evaluate the impact a propeller model has on the free surface near the stern and how this affects the resistance components of a self propelled ship.
