文摘
- •
Surface pressures on the airfoil section were measured by a multiport pressure device.
- •
Static turbulence grids were used to adjust the turbulence intensity in wind tunnel.
- •
Stall phenomenon was discussed at different turbulence intensities and Reynolds numbers.
- •
The flow was separated at the leading edge without grids.
- •
In the cases of with grids, the flow separated region was expanded with the increase of angle of attack.
