Frequency response of a liquid sloshing in a rotating, laterally oscillating, cylindrical vessel

Frequency response of a liquid sloshing in a rotating, laterally oscillating, cylindrical vessel

We have investigated the free-surface fluctuations of liquid in a rotating, laterally oscillating, cylindrical vessel. In the experiments, we changed independently both the lateral forcing frequency f and the rotation frequency Ω of the cylinder. We measured the time-dependent fluid-dynamic pressure...
