Abstract

This paper deals with suppression of sloshing in a vessel by a flexible bulkhead which divides the container vertically into two sections. The sloshing mode is separated into two modes by the bulkhead ; the one is the sloshing mode of liquid column in a U-tube, and the other is the sloshing mode in the each separated container. The effect of flexible bulkhead on the suppression of sloshing is examined with changing the thickness of the bulkhead plate experimentally. The flow pattern in the container is visualized.
