Hydrodynamic damping of liquid sloshing in ship tanks

摘要

This paper describes an investigation of the influence of hydrodynamic damping on the hydrodynamic loads and fluid surface elevations in a ship tank undergoing multiple component motions. A theoretical damping model for horizontal and vertical baffles in the tank has been developed. Experimental measurements of hydrodynamic damping have been carried out to validate the theoretical model, and to investigate the effectiveness of various baffle configurations. It is found that baffles can be used efficiently to damp liquid motions near resonant conditions.
