- •
Surface pressures on the airfoil section were measured by multiport pressure devices.
- •
Turbulence grids were used to adjust the turbulence intensity.
- •
Dynamic stall was shown at different turbulence intensities.
- •
In the case of Re = 1.5 × 105, flow was separated at the leading edge of the x/c > 0.1.
- •
In the case of Re = 2.0 × 105, flow was delayed attachment with the increase of turbulence intensity.
