Tarbiat, S., Lavrov, A. e Guedes Soares, C. (2015), “Numerical simulation of the free surface turbulent flow of a Wigley hull with trim and drift angle”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 1009-1018
The steady free surface flow around a Wigley hull is studied considering different trims and various Froude numbers. The total resistance coefficient is calculated for different Froude numbers from 0.250 to 0.408. A local-time stepping solver is used to solve the Reynolds Averaged Navier-Stokes equations with the k-w turbulent model, using the OpenFOAM software. The domain size has been constant following the ITTC recommendation. A grid independence study has been carried out to insure the best discretization level. The total resistance coefficient and wave profiles are compared against experimental results and it is shown that results are in the good agreement with experimental data. Calculations are also made with the ship model in various drift angles in order to obtain the hydrodynamic derivatives required for the maneuvering equations.
