ABSTRACT

Internal submerged components strongly influence the slosh dynamics of liquid storage tanks and submersed baffles are used for slosh suppression over a long period of time. The effect of a circumferential baffle on dynamic behavior has been analyzed experimentally as well as numerically by various methods. The baffles constrict the flow and modify flow pattern in the tank. These baffles are found to be more effective near the surface than at the bottom. However, use of a solid baffle attaches considerable weight penalty which is substantial when considered in the context of spacecraft and mass liquid carriage vessels. To reduce the weight penalty as well as to ensure uniform velocity distribution in the tank and to smooth out peaks and valleys in the damping due to series of baffles, perforated baffles are widely used as slosh suppression devices. Several experimental studies are performed to understand the effect of perforated baffles but very few numerical studies are reported. The purpose of this study is to understand and examine numerically the effect of perforation in horizontal baffles on the slosh dynamics of a partially filled rectangular liquid tank. The sloshing is studied using a weak-form Galerkin finite element model.
