Steep wave effects on a large-diameter vertical circular cylinder

초록

The objective of this paper is to suggest modified coefficients for estimating horizontal forces on a cylinder of large diameter in steep waves using Computational Fluid Dy-namics (CFD). For those who are interested in estimating wave forces, the use of CFD as described in this paper can reduce required analysis times, providing predicted wave force values which may be useful for early stage designing. A comparison of fully- nonlinear numerical results with the Morison equation and Faltisen Newman Vinje model developed by Faltisen et al. (1995) is conducted to yield each correct co-efficient, respectively. The modified Morison equation and FNV model show good agreement with the CFD results.
