. From the analysis results, the wave run-up at the downstream part
of the cylinder, especially at the specific location near θ ¼ 0° (or
θ ¼ 360°), is not sensitive to the geometry of the cross-section
Fig. 12 shows the maximum dimensionless wave force in the x- and y-direction versus the rotational angle in one period. The
maximum wave force for the case of nr = 1 is almost equal to the
maximum wave force of the circular cylinder, which can be the
oretically proven to be 0.275 and 0 for FX
and FY , respectively. The

rotation angle decrease and the wave force in both directions
