Relaminarisation and wall-functions in CFD

L.Carvalho

Hello!

I hope someone can help me to understand this whole process of relaminarisation due a high flow aceleration (in an inlet of a gap, for example). I have heard that if the relaminarisation process is to be represented then one needs to use a good low-Re model with characteristics in accelerating flow. (1) Does it mean here a low-Re Model as a wall-function? (2) How could I modell it in a CFD-Code? (3) Could anyone give me some references about this topic?

Thanks in advance
