Breaking Water Waves
I am interested in discussing the use of CFD for modeling of breaking water waves. Using Fluent, I have used a transient Volume of Fluid (VOF) model along with 1st, 2nd, and 3rd order solution schemes. Simulation were performed using laminar and standard k-e models. The smallest grid spacing has been 2cm X 1cm (the domain is approximately 2.5m X 23m).
My main concern is "energy" dissipation. The waves lose energy quickly (numerical dissipation is thought to cause this).
Has anyone had succesful, physical results? What sort of schemes have you used? Have you tried adjusting the constants in the k-e equations?
