Experimental Study on Free Roll Decay Motions of a Damaged Ship for CFD Validation Database [PDF]
Journal of the Society of Naval Architects of Korea, 2012 Among many factors to be considered for higher safety level requirements, the hull stability in intact and damaged conditions in seaways is of utmost importance. Since the assessment of a damaged ship is complicated due to the highly non-linear behavior, it is widely acknowledged that computational fluid dynamics (CFD) methods are one of the most ...

Experimental Study on Estimation of Roll Damping for Various Midship Sections [PDF]
한국해양공학회지, 2019 The magnitude of the roll motion of a floating structure depends on the roll damping acting on the body. In other words, the roll damping of a floating structure must be accurately obtained in order to precisely evaluate the roll motion.

Research on Influence of Tank Sloshing on Ship Motion Response under Different Wavelengths
Applied Sciences, 2022 The motion of the liquid-carrying ship under waves is simultaneously affected by the external wave moment and the sloshing moment of the internal tank, which makes the motion of the ship more complicated.

Bilge-Keel Influence on Free Decay of Roll Motion of a Realistic Hull1 [PDF]
Journal of Offshore Mechanics and Arctic Engineering, 2017 The prediction of roll motion of a ship with bilge keels is particularly difficult because of the nonlinear characteristics of the viscous roll damping. Flow separation and vortex shedding caused by bilge keels significantly affect the roll damping and hence the magnitude of the roll response.
