Sažetak
In this paper, a numerical simulation of a damaged ship model is investigated. The damaged ship model has a hole that involves eight subspaces of the cargo tank between two watertight transverse bulkheads. The damage of the ship bottom, due to possible grounding, equals to the 20% of the total length of the ship. In this paper, the numerical simulation of flow around the hole and inside the tanks and calculation of the total damaged model resistance are carried out by employing commercial software package STAR-CCM+. The mathematical model is based on the Reynolds-averaged Navier-Stokes (RANS) equations, with the Volume of Fluid (VOF) method for two-phase turbulent flow, and the k-ε turbulence model. The mesh sensitivity analysis of the results obtained for the total resistance force of the damaged model is conducted using different mesh resolutions. The numerical results of the total resistance force of the damaged model are compared to the experimental results.
