We expect large vortices downstream the turbine?

We may want to use the following simplifications:

• Assume the airfoils are flat plates of 0.1x2cm, positioned on a pitch angle of 20deg, i.e. the plates are placed such that when they are at the upper-most part its trajectory, they form an angle of 20deg with the horizontal.
• Incoming flow with a constant profile of 10m/s in the horizontal direction
• The downstream pressure is constant 101325 Pa.
• Air with density of 1.225kg/m3 and viscosity of 1.7894e-5 Pa.s. 
• 2D analysis
