Forced liquid oscillations in paraboloid containers
Abstract
The response of the liquid in an arbitrary partially filled tank of paraboloidal geometry to harmonic translational and roll excitation about its axis is determined. Free liquid surface elevation, pressure and velocity distribution are determined as well as the force of the liquid on the container. The motion of the liquid is finally described as a simple mechanical model to which equivalent linear damping is introduced. Experimental results exhibit good agreement with the theoretically obtained values.
