Model Experiments and Simulations of a Damaged Ship With Air Flow Taken Into Account

Abstract

To study the motion behavior of a damaged frigate, tests have been performed in calm water and in waves of different heights and periods. The paper contains comparisons between experiments and simulations for selected conditions that highlight the effect of air flow. Particular attention is also paid to transient flooding and roll transients, and to the effectiveness of cross-flooding arrangements. Significant air flow has been observed during the experiments, and the paper aims at assessing the importance of the phenomenon in modeling the behavior of the vessel.
