Couplage fluide-structure en construction navale
Fluid-structure interaction in ship structures
Institut de Recherches de la Construction Navale
Fluid structure interaction is a key phenomena in the numerical simulation of the dynamic behaviour of ship structures. Considerable research efforts have been continuously carried on, but though many advanced tools are available, a numerical mock up approach is far from being used. This is mainly due to insufficient accuracy or reliability of these tools. Numerical simulations are therefore used complementary to experimental methods performed in large basins and correlated with long records of measurements. In most cases, ship structure dimensioning is rule based, using classification societies requirements. The study of ship vibrations induced by oscillating forces due to auxiliary and main engine and pressure variations due to the propeller is well mastered and the numerical simulation is then a standard design tool. The increasing size, speed and complexity of new ships such as high speed crafts raise new dynamic problems and IRCN contributes to the development of numerical tools allowing a direct approach of the design of such ships.
