... good, due to the large influence from vicsous roll damping, which is missing in these calculations. This paper proposes a hybrid method, as a solution to this problem, where the viscous roll damping from Ikeda's semi-empirical method is injected into an existing 3D unsteady fully nonlinear potential...

... Abstract A multi-domain method incorporated with higher-order boundary element method is proposed to calculate large amplitude ship motions with high accuracy and stability, in which the Rankine panel method and free surface Green's function method are applied in the inner and outer domain...

... Abstract The external loads and ultimate load-carrying capacity are two important aspects to evaluate the safety and reliability of the ship. In this study, fluid-structural interaction calculation and model collapse test are combined together to obtain the ultimate strength of an aluminum...

... at the wellhead slot of the platform. Because the most section of the riser is submerged in sea water, it is often in a state of vibration induced by waves and currents, which may cause fatigue damage to the structures (API RP 2RD, 1998). Riser dynamics calculation is a basic step to obtain installation...

..., and based on this, the ship was designed reasonably to reduce the impact of bubbles on the hull. In this paper, DTMB5415 is taken as the research object, DES model and Lagrange particle are adopted, DDES is selected for numerical calculation, and the relationship between bubble trajectory, bubble particle...
