Sloshing in a rotating liquid inside a closed sea cage for fish farming

Abstract

Sloshing in a sea cage with a slowly rotating liquid is investigated. The cage is axisymmetric, and the liquid is subjected to a nearly uniform
angular velocity about the vertical axis of the cage. Both experimental and theoretical investigations are presented. It is shown that rotation
modifies the sloshing regimes of a non-rotating liquid by splitting the natural frequencies. Therefore, resonant sloshing regimes can be
manipulated by varying the rotation rate of the liquid.
