Abstract

This paper focuses on the inline force and bow wave height on a surface–piercing vertical cylinder moving at a constant forward speed in calm water and in waves. A Computational Fluid Dynamics (CFD) model has been developed using Caelus® open source code. A stationary mesh was developed and the wave libraries were modified to generate current of a speed equal to the velocity of the moving cylinder while still prescribing the desired wave profile. The capability of the CFD model has been illustrated by the very good agreement achieved against results from physical experiments performed in a towing tank for various conditions of increasing complexity.
