Turbulence model selection in FLUENT

Kim yongchul · December 5, 2017, 04:56

Hello,

I would like to know the selection of turbulence model if i use 10 m/sec as inlet velocity to simulate my airfoil model.
When should i choose the turbulence model in FLUENT.
Sorry for silly question.
Thanks

If the question is 'when' it's when you're in fluent pre, where you set up the boundary conditions and materials. In particular where it says Models -> Viscous -> selection.
For airfoils you could used k-epsilon (realizable) or k-omega (SST) as a first approximation, and if you need something better you should look up this particular problem in the literature, and depends on your objective, if you need to make up larger structures in the flow and so on.
