Dynamics of Partially Filled Rectangular Rigid Tank with Surface Piercing Elements
摘要
Slosh dynamics of partially filled liquid tanks are greatly influenced by the presence of structural components within the liquid. The effectiveness of these structural elements depends on various factors such as position, thickness and flexibility. These elements add considerable weight penalty and modify the flow characteristics in the fluid domain which are cause of concern. Baffles are one type of internal components that are often used to suppress sloshing motion of the liquid. Efforts have been made to select the baffle configuration which is most effective and affects the other parameters least. Surface piercing baffles are considered as one of the most effective tools that change the dynamics of partially filled tank with least weight penalty and cost. A surface piercing baffle can also be designed as retrofitting element for those fluid containers which are not originally designed on dynamic consideration. So far numerous theoretical and experimental studies are carried out to investigate the effects of surface piercing baffles in containers of various shapes but numerical studies are scarce. This study aims to understand the effects of surface piercing baffle on slosh dynamics of rigid rectangular tanks numerically using pressure based finite element method. The study also includes combination of bottom mounted baffle and surface piercing baffle.
