As an effective anti-sloshing device, a reversed U-tube was employed as a dynamic damper and its suppression characteristics were studied for the case of a cylindrical tank which was forced to oscillate horizontally. As a result, the following was found: A single U-tube has enough capability to suppress resonant sloshing when the tank is oscillating in a direction parallel to the U-tube. but it fails to suppress the resonance against the excitation in a direction perpendicular to the U-tube. When two U-tubes are set in the cross form in the cylindrical tank, they can suppress resonant sloshing against the excitations of any directions. The frequency responses of the surface elevation calculated by the Boundary Element Method show good agreement with those obtained by experiments.
