CFD Based Hull Hydrodynamic Forces for Simulation of Ship Manoeuvres

Tabaczek T., Gornicz T., Kulczyk J.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2009

Vol. 3, no. 1

31--35

There have been developed numerous mathematical models describing the motion of a ship. In opinion of present authors the CFD is mature enough to determine with confidence the hydrodynamic characteristics necessary to simulate ship manoeuvres. In this paper the authors present the attempt to determine the hull hydrodynamic forces using the results of CFD computations of ship flow. Results show qualitative agreement with reference data and reveal shortcomings due to simplifying assumptions applied in CFD computations.

Model of Interaction of Water and Tank’s Structure in Sloshing Phenomenon

Krata P.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 4

389--395

The paper presents the model of interaction between ship’s tank structure and water contained in the tank. The experimental investigation of sloshing loads in ships’ tank is characterized and the need for description of mutual influence is underlined. The model of interaction is made up for rectangular ship’s tanks and it is assumed to be in time-domain and nonlinear. The solution is based on the data obtained by the experimental research and numerical simulation. The study may be the contribution to more sophisticated estimation of ship’s stability than it takes place nowadays.
