Turbulence Schmidt Number for AV
What is the Turbulence Schmidt Number used for the diffusive term for additional variable transport equations? I expect it is 2 for kw, but what if a keps is enabled where the Sc,t is different for the equations?
Background: I am using additional variables (AVs) for a turbulence model. As a test, I implement kw model for a mixing layer. For a first step, I am setting source terms based on CFX k and w. Thus, the k and AV k equations should have the same source terms. I expect that my AV k will be pretty close to CFX k. However, there are differences. For this problem this can only be the diffusive term Thanks 
As I recall, the default Turbulence Schmidt Number for species transport equation is 0.9.

Thanks that seems to have done it
Next question is how to change? What if no heat transfer option is set? 
TURBULENT FLUX CLOSURE:
Option = Eddy Diffusivity Turbulent Schmidt Number = ?? END 
I was wondering if there are other options for Option = ...
I would like to have a different turbulent diffusivity for the scalar equations than the momentum equations. I have tried doing this by having a fancier function for the kinematic viscosity setting at the Domain Level. However, it seems to be more restrictive on the variables being passed than say at the Subdomain level for the source terms.
