WAVE FORCES ACTING ON A HORIZONTAL CIRCULAR CYLINDER INCLINED TO THE WAVE CRESTS

Inertia forces on a horizontal circular cylinder in waves significantly decrease with increasing Kc number at low Kc numbers. The authors discuss how the inertia force reduction can be explained using a simple vortex shedding model. On the basis of this model, it was deduced that the inertia coefficient in regular waves is given by a simple formula, Cm=2(2/pi 2) Kc2. In this paper, the formula is extended to an inclined cylinder horizontally submerged in regular waves. The extended formulas are in good agreement with the experimental results at Kc less than 2.5 for any inclination angle.
