Twenty-First Symposium on NAVAL HYDRODYNAMICS
The results presented here show the ability of fully coupled method to take into account the exact free surface conditions and to solve the kinematic condition near the hull in spite of the singularity of equations at free surface and hull intersection. However the finest grid size seems too coarse to compute well free surface elevation, pressure velocity field and especially turbulent quantities.
The continuation of this work will consist in perform calculation with finer mesh to obtain grid independency results (perhaps around 500 000 or 600 000 nodes). After this step it will be possible to consider the problem of turbulence modelisation and the influence of various schemes.
Short-dated study will concern comparisons between k-ε and k-ω turbulence model. Calculations on yawed hull and turning hull will be the long-dated work.
