抄録

Inertia force on a horizontal circular cylinder in waves significantly decreases with increasing Kc number at low Kc number. The authors reported that the inertiaforce reduction of the horizontal cylinder can be explained by 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/π^2)Kc^2. 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.
