Measured 2-dimensional damping forces of baffles with various shapes and perforations are presented for fluid conditions representative of those in liquid fuel rockets; effects of amplitude and frequency of fuel sloshing, and surface proximity on baffle damping are shown; application of results in prediction of damping effectiveness of ring baffles in cylindrical tanks is demonstrated.
