The aim of this investigation is to assess the influence of
viscous effects on the predicted hydrodynamic coefficients for a
range of ship-like sections, such as rectangular, triangular, chine
and bulbous. Hydrodynamic coefficients, of added mass or
inertia and fluid damping, for two-dimensional sections
harmonically heaving, swaying and rolling at the undisturbed
free surface are obtained using the ANSYS-CFX11.0 RANS
solver, for a range of frequencies of oscillation. All predictions
are compared with available experimental measurements and
other numerical predictions (potential flow and RANS). It is
concluded from these comparisons that the proposed RANS
approach can offer a better prediction for the hydrodynamic
coefficients when viscous effects become significant, in
particular for sway and roll motions. It is important that a
reliable and systematic approach is adopted for the application
of the unsteady free surface RANS methodology.
