Hi all,
I'm working on a low Re (~220000), low AR (~1.5-2) MAV model, and I'm now confused with which turbulent model to use. I realise that if I want to use k-epsilon and k-omega, I will need Y+ to be about 30, while if I use k-omega with the transitional flows option enabled, I will need Y+=1. So I want to decide which is a better model for my case before generating the grid. Could anyone give me a hint and recommend a good book on this? There are also some variants of both models, please could someone explain their differences (or are they just much the same)? xxxx |

Refer to the UG... in Fluent use TUI (text user interface) from there you can find more turbulent models....

I acutally read the UG before I post the question: Nothing much says about which model is better for low Re. The only reference to Re is that k-omega can be used for both high and low Re situations.
