Default Curvature Correction For A Circulation Control Airfoil

Jorg is on a distinguished road

I'm trying to simulate a Circulation Control Airfoil using the Spalart-Almaras turbulence model, however when setting high velocities in the jet slot boundary condition the tangential flow detaches from the airfoil in the middle of the lower surface.

This phenomenon has two adverse effects:
The simulation which is initially steady becomes transient and,
The drag coefficient has values between 0.1 and 0.7

żDo you know any mean to modify the Curvature Correction in the Turbulence model inside fluent to solve this problem?
