Title: Forces on Vertical Cylinder Due to Random Waves
Abstract: Random wave forces consisting of drag and inertia components are analyzed. The forces were measured in a wave tank experiment with circular cylinders at low Keulegan‐Carpenter numbers. The values of the hydrodynamic coefficients were chosen from the corresponding tests in regular waves. The method used in choosing these values applicable to the case of random waves is discussed. The nonlinear drag force contribution is linearized so that the spectral approach may be applied directly. Good correlations between the measured force spectra and the computed spectra were obtained in several cases of random waves. The short‐term distribution of the in‐line and transverse forces is shown. It is found that the in‐line force amplitudes follow the Rayleigh distribution reasonably well. The relations of the transverse force to an exponential distribution are exhibited.
