K-epsilon and k-omega discrete and algorithm

fasisisido · February 11, 2012, 08:49

Hi guys,

I search a lot but don't find anything about how to discrete k-epsilon and k-omega turbulence models. I believe I google wrong words

Can anyone here show me how to discrete these two turbulence model equations.

I also need an algorithm that how software (like SSIIM) solve these equations. which steps do they take to solve these equations

Thanks

Hi,
I don't have the equations here before me, but if I'm not mistaken, their are just hyperbolic/parabolic equations for k, eps and omega.... So you can just discretize them in the way that you discretize your NS equations!

Cheers!
