v2f Turbulence Model (and others?)

January 5, 2009, 14:25

Two questions:

1. Does anyone have any case studies that would help determine the accuracy of the v2f turbulence model for highly turbulent flows? I'm trying to decide on a turbulence model for a circulation-control wing.

2. What other turbulence models are built into FLUENT? I only found out about the v2f model recently and I'm wondering if there are others I don't know about.

Thanks,

some Low Reynolds Number (LRN) version of k-e models also available in fluent.

Any idea how to activate them? I know the command for the v2f model is (allow-v2f-model).

To enable LRN k-e. First choose the std k-e model and then type the following in the console window define/models/viscous/turbulence-expert/low-re ke yes

after this you will get the LRN k-e model in the viscous panel.

hai

anybody know how to impliment the zero equation model. what is zero-equation-havac thanks in advance
