Dynamic Behavior of Stratified Fluids in a Rectangular Container Subject to Vertical Vibration

抄録

A theoretical and experimental study is presented for the dynamic behavior of two liquid layers with a free surface in a container subject to vertical vibration. This study is concerned with two fluids sloshing phenomena. The stabilities of the plane free surface and interface of two superposed fluids with different densities are analyzed theoretically. In the analysis, the two liquids are ideal fluids, the interfacial surface tension is considered, and wall contact effects are neglected. An experiment was made on vertical vibration of a rectangular container holding kerosene and water. The agreement between theory and experiment was satisfactory on the occurrence of 1/2-subharmonic wave motions. The response amplitudes of the free surface and interface wave motions were measured. Many drops formed by the interfacial disintegration were observed in the lower fluid.
