Changing k-e constants to functions
Hi all,
I'm working on a user-defined v2-f turbulence model for FLUENT (I know it has one, but I'm trying to make one with curvature correction.) The model uses the standard k and e transport equations that the k-e model uses. The transport equations are the same, but the constants are different. In particular, the C_1e constant is different. For the k-e model, C_1e = 1.44 For the v2f model, C_1e = 1.4*( 1 + .05*sqrt( k/v2 ) ) Does anyone know how to change the C_1e constant to a function? Thanks in advance. |
Ok, I figured out how to add an additional source term to the epsilon term (DEFINE - BOUNDARY CONDITIONS - FLUID - SOURCE TERMS). I coded my source term, added it as S_e in the epsilon transport equation, and set the C_1e and C_2e constants to 0 in the DEFINE - MODELS - VISCOUS menu.
Now I have another question. I can't figure out how to change C_1e and C_2e using text commands. Is that possible? |
