Abstract
In the paper, a CFD solver is applied to study the roll coefficients of a appended ship model with forward speed. Two approaches based on RANS and VOF modelling are adopted, namely, roll decay and forced roll motion. The results of roll coefficients from two approaches are compared and validated against model test data. The effects of viscosity on the hydrodynamic coefficients are studied by solving Euler equation. Additionally, the numerical simulation of forced roll motion at full scale is performed. The present results show that the influences of viscosity and scale on hydrodynamic coefficients except ship resistance are not large.
