Experimental Investigation For Liquid Sloshing In Baffled Rectangular Tanks

Abstract- Liquid sloshing is a kind of very complicated free surface flow and exists widely in many fields. In this paper the sloshing phenomenon in a partially filled rectangular tank under a sway excitation is studied experimentally. A small scale test rig is designed and constructed to measure the dynamic tank wall forces and interaction forces the baffles are fitted to attenuate the lateral motion of the liquid slosh. Lower mounted and upper mounted vertical baffles of different heights are tested. Lower mounted vertical baffles with central hole of different sizes are considered. The results show that the size and position of the vertical baffles significantly improve damping.
