Wave Force Tests on Vertical and Inclined Cylinders

A wave tank test was performed on fixed vertical and inclined cylinders in which forces on the cylinder in regular waves were measured. The hydrodynamic coefficients are computed based on the measured local forces on the cylinder, Morison equation and stream function theory. The inertia and drag forces are shown as functions of the Keulegan‐Carpenter number. The lift coefficients and lift force frequencies are presented as functions of the Keulegan‐Carpenter number. The coefficients obtained locally are shown to generally apply to the entire cylinder based on the respective local KC values.
