CFD Analysis on Flare Slamming Load of Container Ships
Based on the CFD method,the effects of wavelength and wave height on the motion and flare slamming of KCS ships under wave conditions are studied.The spatiotemporal distribution of slamming pressure and its relationship with the vertical motion are analyzed.Based on the open-source wave-making tool waves2Foam,a three-dimensional numerical water tank is established,and the overset grid technology of the naoe FOAM-SJTU solver is used to solve the motion of ships in waves.The results indicate that the amplitude of ship motion increases with the increase of the wavelength and wave height,and the flare slamming pressure is the highest at λ/LPP=1.The flare slamming pressure increases linearly with the increase of the wave height.Container ships should avoid sailing in sea conditions with a wavelength close to the length of the ship.This study can provide a reference for predicting ship-slamming loads in waves.
