Multidomain LES/RANS

January 27, 2005, 16:44

Hi all, I wanted to couple two domains, one with a RANS solution and one with a LES solution. Sagaut's book tells me exactly what to do with velocity and even viscosity.

My question is: what to do with pressure? Should a set grad (Ples) = grad (Prans) at boundaries? (I am mostly worried about "inlet" boundaries).

Thanks all.

Hi John, Still, none of them specify how to treat pressure in the frontier... Any idea? Thanks.
