Numerical Modelling and Simulation of Ship Hull Geometries

Abstract

We consider the numerical optimization of the geometry of ship hulls with the Voith–Schneider r Propeller (VSP), an efficient propulsion and steering device. The presence of one or more VSP sets some requirements to the ship hull. We describe modeling, simulation and optimization of such geometries as a four step chain. First, we introduce a geometrical model of the ship hull plus attachment parts. Second, this model is transformed into a computational mesh which is used in Computational Fluid Dynamics (CFD) in the third step. The numerical optimization is the fourth part. Our method is fully automatic. We show some numerical results.
