Validation and verification of hull resistance components using a commercial CFD code
Validation and verification of hull resistance components using a commercial CFD code
A mathematically defined Wigley hull form is used to investigate the application of a commercial CFD code in prediction of the total resistance and its components from tangential and normal forces on the hull wetted surface. The computed resistance and wave profiles alongside the hull were compared with experimental observations for six different Froude numbers to validate the simulations. The effects of grids, domain size and turbulence models were studied. A statistical hypothesis test was carried on these resistance data in order to determine the most suitable turbulence model for the lowest and highest Froude numbers.

Abstract
A mathematically defined Wigley hull form is used to investigate the application of a commercial CFD code in prediction of the total resistance and its components from tangential and normal forces on the hull wetted surface. The computed resistance and wave profiles alongside the hull were compared with experimental observations for six different Froude numbers to validate the simulations. The effects of grids, domain size and turbulence models were studied. A statistical hypothesis test was carried on these resistance data in order to determine the most suitable turbulence model for the lowest and highest Froude numbers.
