problem with bondary condition for RANS case for NACA0012 using FLUENT

I am running RANS simulation for NACA0012 aerofoil to use the RANS result as initial solution for incompressible LES simulation. My simulation domain is 3 c upstream, 7 downstream and 3 c to upper and lower boundaries. The simulation is using k-w SST and i run it for angle of attack 10.8. I used two boundaries as inlet (velocity inlet) and i define the velocity components ( ucos(10.8),usin(10.8),0) and other two as pressure outlet, while the front and back are periodic.

the velocity contours and outlet velocity profile are shown below

and the outlet pressure boundary 

has anyone face the same problem at the outlet boundary as shown in the velocity profile at the outlet boundary?
