Ships feature superstructures and components with steps, recesses and styling surfaces that lead to flow separation. A favourable air flow becomes a design criterion, particularly for mega-yachts and cruise ferries. For instance, exhaust gases should be kept from passengers and crew. This paper shows how CAD (Computer Aided Design) and CFD (Computational Fluid Dynamics) can be coupled for aerodynamic design. An example of a mega-yacht is studied. Systematic refinements were undertaken to clarify the levels of detail necessary for resolving geometry and fluid domain. Subsequently, the funnel was optimised in order to improve emissions.
