Abstract

The effects of a vertical baffle on the resonant frequencies of fluid within a rectangular container are investigated using the linearized theory of water waves. The accuracy of simple approximate solutions is assessed by comparison with an accurate solution based on eigenfunction expansions. It is found that a surface-piercing barrier can change the resonant frequencies significantly while the effect of a bottom-mounted barrier is usually negligible.
