Fluent parameters for sailing yacht analysis

Daniel

Hello,

I am looking at the CFD analysis of an America´s Cup yacht in Gambit and Fluent and I was wondering if any of you can advise me on the parameters and boundary conditions one might use to obtain proper results.

I am concentrating on the hull and the appendages and plan to look for upright and heel condition (10-15-20-25 degrees). I do not take into account the geometry above the free-surface (waterline) and from the Gambit model, I have some initial conditions like wall surfaces for the yacht and the appendages, inlet velocity at inlet, outflow/pressure outlet at outlet, symmetry at centreline (for upright condition).

Any advice on turbulence modelling, advection scheme etc... would be very welcome!

Thank you for your help,

Dimo
