Zusammenfassung:An experimental investigation was conducted to determine the effects of baffle configuration, width, and location on the damping characteristics and frequency of the fundamental antisymmetric mode of liquid oscillations in rightcircular cylindrical tanks. Baffle configurations studied include fixed rings, rings with radial clearance, cruciforms, and conic sections. For the conic-section baffles, upright, inverted, and perforated configurations were examined. Some results of studies of effects of amplitude of the liquid oscillations and kinematic viscosity on the damping are also presented. The damping results obtained in the investigation are in agreement with those predicted by available semiempirical analytical methods. (Author)
