Analytical and experimental evaluation on the effectiveness of upper mounted baffles with respect to commonly used baffles

► Upper mounted baffles has a great potential as a sloshing suppress device. ► Developed analytical solutions have enough accuracy to utilize for baffles design. ► Horizontal baffles have significant damping effects in slender tanks. ► Vertical baffles are more effective for broad tanks. ► Overall, horizontal baffles are more efficient, but less economical.
