Practical application of computer-aided hydrodynamic ship design V. Bertram" & J. Laudan* "Institut fur Schiffbau, University Hamburg, Germany * Hamburg Ship Model Basin, Hamburg, Germany ABSTRACT Computational fluid dynamics (CFD) can improve hull design for cer- tain ships. The most important CFD methods are panel methods and 'Navier-Stokes' solver. Panel methods compute the inviscid free-surface flow (wave resistance) to evaluate the forebody. 'Navier-Stokes' solver allow eva- luation of the aftbody simulating viscous flow usually neglecting free-surface effects. Basic assumptions for both methods are reviewed. Practical appli- cations include a container vessel, a ferry, a SWATH ship, and a tanker. INTRODUCTION The development of new ships still is a slow evolutionary process. Series are generally small and time for development of a new ship is generally too short. There is no opportunity for modifications after intensive testing of a prototype, since the prototype is
