摘要

In this paper, an experimental and an analytical investigation of the hydrodynamic damping due to lower and upper mounted vertical baffles as well as horizontal baffles in partially filled rectangular tanks are conducted. The analytical model earlier provided to estimate the hydrodynamic damping ratio of lower mounted vertical baffles is extended for upper mounted baffles. The semi-empirical Miles expression, which was originally developed to evaluate damping ratio of ring baffles in cylindrical tanks is also formulated for horizontal baffles in rectangular tanks. The comparisons between maximum hydrodynamic damping cased by various baffle configurations (upper and lower mounted vertical arrangements, as well as horizontal arrangements) are made and the validity of extended analytical models is discussed.
