Experimental observation on violent sloshing flows inside rectangular tank with flexible baffles

Year: 2024

Type: article

Abstract: In this study, a series of sloshing model tests were conducted to observe the effects of an internal baffle in a rectangular tank and to secure basic data for future numerical calculations or applications to similar phenomena.The sloshing flows and flexible motions of two different baffles with hyper-elastic properties were observed and the results were compared with those of a non-flexible baffle. Experiments were conducted for different filling conditions, motion amplitudes, and excitation frequencies, with a particular focus on violent flow cases. The local flows around the baffles were captured using a high-speed camera, and the sloshing-induced impact pressures on the tank walls were measured. The present experiment showed strong interactions between flexible baffle motion and sloshing flows, particularly at motion frequencies higher than the natural sloshing frequency. The physical phenomena became more complicated when the free surface was closer to the baffle height. The data obtained in this study can be used as benchmark tests for numerical computation of strong-fluid interactions.
