Abstract: 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.
