In the present paper a comparison is made between full scale measurements and numerical predictions of the dynamic pressures due to sloshing phenomena in the tank of a ship at sea. The full scale measurements were obtained in the ballast tank of a Bulk-Carrier during a crossocean voyage. The motions of the ship were as well measured by means of a gyro-stabilized platform. The numerical calculations were performed by means of the LRFLUIDS program, kindly provided by Lloyd's Register of shipping. The influence of the main parameters involved in the computation is discussed in the work, with reference to the two components (impulsive and not impulsive) of the dynamic pressure on the walls of the tank.

Abstract

In the present paper a comparison is made between full scale measurements and numerical predictions of the dynamic pressures due to sloshing phenomena in the tank of a ship at sea. The full scale measurements were obtained in the ballast tank of a Bulk-Carrier during a crossocean voyage. The motions of the ship were as well measured by means of a gyro-stabilized platform. The numerical calculations were performed by means of the LRFLUIDS program, kindly provided by Lloyd's Register of shipping. The influence of the main parameters involved in the computation is discussed in the work, with reference to the two components (impulsive and not impulsive) of the dynamic pressure on the walls of the tank.
