• Two-layer sloshing
• magnetic fluid
• linear theory analysis

This study investigates the behavior of two-layer sloshing using a magnetic fluid and silicone oil. To obtain basic relations, a linear theory is employed. After obtaining those relations, theoretical values of free-surface displacement, resonant frequency, and resonant pressure amplitude are compared with experimental results. Experimental data are obtained using a laser sensor and four pressure transducers. Free-surface displacement is measured by the laser sensor. Resonant frequency is measured by both the laser sensor and pressure transducers. Resonant pressure amplitude is recorded by the pressure transducers. The results demonstrate that the theory employed in this study is effective as a first estimation of two-layer sloshing. However, to describe the behavior of a two-layer magnetic fluid sloshing more precisely, a nonlinear analysis that considers magnetic force is necessary.
