Simulation of Flooding of a Ship After Damage with Computational Fluid Dynamics

 

The issue of survivability of ships after flooding due to damage or collision is a debating issue for the maritime community for more than one century now. The flux of floodwater in the complex internal compartmentation of a ship is influenced by numerous factors and has a substantial impact on ship motion. Scientists and engineers, trying to understand and to take practical decisions during the design process, have developed simplified models with questionable assumptions and simplifications of this complex hydrodynamic problem.

The aim of this work in the investigation of this problem with the use of the modern Computational Fluid Dynamic Tools. For the simulations, the OpenFOAM,open source CFD Library, is used. The computational approach is based either on the solution of full Navier Stokes for the flooding in calm water or the coupling of Non-linear Potential Flow with Navier Stokes for the simulation of the flooding in waves. The coupling between the Non-Linear Potential and Navier Stokes solver based on the Collaborative Computational Project in Wave Structure Interaction (CCP – WSI**) funded by EPSRC.
