Re: Low Speed Airfoil
That's a laminar separation bubble, and you're not easily going to model that in Fluent. If you run Fluent with no turbulence model, it will probably predict separation without re-attachment there. With a turbulence model, it won't know about the separation bubble. There are ways and means of suppressing the turbulence model where you know the flow to be laminar, but in that case, is there any point in doing the CFD? What's wrong with using Xfoil or Msis for this study?
