Abstract

Ship added resistance is a steady force of the second order which depends on the ship motions and wave diffraction in short waves. To predict the impact of liquid motions inside the ship hull, a flooded tank in the midship area is generated and the ship response to regular waves is calculated. Currently available mathematical models and numerical tools are used to enable new insights into the sloshing effects of a relatively large free surface of flooded water inside the ship hull. The liquid inside the tank is first considered as a solid body in order to make a distinction between the hydrostatic and the hydrodynamic effect on global ship motions. Source formulation panel method is used and wave loads acting on the ship hull are determined using the near-field formulation. Based on the potential flow theory, the influence of sloshing on the ship motions and added resistance is evaluated to get an insight into this complex hydrodynamic problem. The calculated results are compared with the available experimental data from the literature.
