Abstract
An experimental investigation is conducted to explore the effectiveness of porous baffles placed at l/3 and 2l/3 in the sloshing tank. A tank aspect ratio, hs/l of 0.488 which corresponds to 75% filled condition is considered. The sloshing tank is kept inside the freely floating barge and subjected to regular beam sea waves. A wave height of 0.1 m and excitation frequencies ranging from 0.45 Hz to 1.54 Hz is adopted. Baffles with three different porosities of 15%, 20.2% and 25.2% are used. The effectiveness of baffles placed at l/3 and 2l/3 is explored on comparison with the performance of single porous baffle kept at l/2 and a solid submerged baffle place at l/2. Sloshing dynamics for the baffles placed at l/3 and 2l/3 and barge responses are also discussed.
