I am running a turbulent incompressible flow on an airfoil. for angle of attack of 10 or more degrees Spalart almaras model gives negative drag. should I modify turbulent parameters? or any idea???

I have been modelling airfoils for a while for my final year project, it is defiantly your force vectors-sorry.
