主 题：Gap resonance low-frequency incident wave heave motion constrained interpolation profile(CIP)
摘 要：The fluid resonance of a moonpool freely heaving in a beam sea is studied by an in-house constrained interpolation profile(CIP)***,the moonpool behaves as in the piston mode with a narrow *** numerical studies are carried out for a wide range of the incident waves,and a new secondary resonant region is identified in the low frequency region of the incident waves,besides the ordinary main resonant *** results demonstrate that the horizontal wave forces are significant in the secondary resonant region,although the resonant wave elevations are less remarkable than those of the main resonant *** is concluded that the fluid resonance of the low frequency is excited mainly by the heave motion of the *** studies of the moonpool draft and the gap width of the moonpool based on the fluid resonance are also performed.
