k-epsilon parameter setting in Elmer

Post by hola »

Helo,

I'm uncertain about how to set k-epsilon parameters in Elmer.
Short overview:

Turbulent kinetic energy: ([0.16*Re^(-1/8)]^2 ) * 1.5
dissipation: [k^1.5/(characteristic length)] * (model constant=0.09)

reference source: http://www.cfd-online.com/Wiki/Turbulen ... conditions

subsection 1.2 and 1.3

Do I have to set the model constant in Material:K-Epsilon:K-E Cmu?
If yes, then I can omit the model constant from the equation above?
What's K-E Clip in Elmer?

Thank you for your help in advance!
