水平加振を受ける回転円筒容器内の液体スロッシングおよびスワーリング

抄録

We investigated the free surface fluctuation of liquid in a rotating cylindrical container which receives horizontal vibration in the horizontal direction. In the experiments, we changed the oscillation frequency f and the rotation frequency Ω. We measured time dependent pressure fluctuation instead of free surface fluctuation. By performing FFT analysis, two significant frequencies f − Ω and f + Ω are obtained, which correspond to wave rotation in the same and in the opposite directions of the container, respectively. We also examined these results using linear wave theory.
