Aerodynamic optimization of superstructures and components
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 2010
Ships feature superstructures and components with s
teps, recesses and styling surfaces that cause
detached flow phenomena. A favorable air flow becom
es a design criterion, particularly for mega-
yachts and cruise ferries. For instance, exhaust ga
ses should be kept from passengers and crew.
Within this paper it is discussed how Computer Aide
d Design (CAD) and Computational Fluid
Dynamics (CFD) are coupled for aerodynamic design.
The FRIENDSHIP-Framework for parametric
modeling and process control and ANSYS CFX for visc
ous flow simulations were combined. The
aerodynamics of a mega-yacht was studied. Systemati
c refinements were undertaken to clarify the
levels of detail for resolving geometry and fluid d
omain. Subsequently, the yacht’s funnel was
optimized to improve emissions.
