Sloshing is created in a rectangular tank model that is filled with 27% water by a reciprocating motion. The pressure forces acting on the side walls due to the free surface deformations were measured via three pressure transducers installed on the side wall. The stages of the free surface deformations during periodic movements of the rectangular tank with and without the perforated baffles were observed via a high-speed camera. It is shown that in the case of perforated baffles, the free surface elevation on the sidewalls, the waveform development and the time at which the maximum pressures were reached were altered due to the modified movement of the bulk liquid. These changes in the liquid movement due to the perforated baffles resulted in 40-60% reduction in the pressure forces acting on the sidewalls. It is predicted that restraining the liquid movement with the use of passive resistance, e.g. perforated baffle, in sloshing may prevent structural damages and increase ship instability.
