EXPERIMENTAL AND MATHETICAL MODELLING OF FLUME ANTI-ROLL TANKS FOR SHIPS

Describes an approach to assessing the performance of flume antiroll tanks. A rolling frame for testing models up to 6 ft. 0 in. beam together with an analog and control system enabling the frame to be used as a ship roll simulator, is described. A linearized mathematical model of fluid motion in a flume is presented. An empirical representation of the principal nonlinearity of flumes is then added. Harmonic responses of a model flume, both with constant amplitude forced rolling and incorporated in a ship simulation, are presented and compared with the mathematical model.
