Turbulent model properties for airfoil
Hi,
I'm trying to solve in fluent flow around part of wing (dimensions:3x0.3x0.3) in 3D with Spalart-Allmaras turbulence model. On the velocity inlet I set turbulence intensity to 5% and lenght scale to 0.3. There where no problems with convergetion in small attack angle. For higher angles solution don't converge. Where could be a problem? Regards, Michal |
Re: Turbulent model properties for airfoil
Hi Mike,
Separation of flow occured (i.e. stall) for the higher angles of attack and it's no longer a steady flow over the wing? :p Good luck. p.s.: An airfoil is not a wing. :p Also at higher angles of attack, you might want to try the SST k-w turbulence model. |
