Abstract

Liquid sloshing is generally caused by external container excitation, and often has significant influence on the response of the container. The liquid sloshing generates significant localized pressure on the tank walls and roof inflicting damage to the constituent parts and in the worst case scenario leads to the complete structural failure. Baffles are used effectively to reduce the sloshing response of liquid in the liquid storage containers by destroying the continuity of the pressure distribution on the wall along the vertical direction. In this study, the damping effect of the horizontal baffles inside a liquid storage tank is investigated. The horizontal ring baffle wall located at two heights equal to 0.8 and 0.9 of the water height was used for the study. A parametric study showed that the ring baffles are effective in reducing the sloshing oscillations.
