Initialization of eps, R, k in the LRR turbulence model
 

Hello,



I am trying to run a case using the LRR model. My case is a pipe with a piece inside that make the flow rotating.
I have some questions concerning this turbulence model:

1/ Do we have to use wall function with this model or we can run it without?


2/ I obtain my R field by running my case using k eps model turbulence. What I obtain is just internal field is it right? If it is, what do I have to put as boundary conditions? My boundary are inlet, outlet and immobile walls




Thank you in advance
