- •
Flow visualization is investigated with blade surface tufts and oil film methods.
- •
Pressures are directly measured by multiport pressure devices in the static state.
- •
Results are discussed at different turbulence intensities and low Reynolds numbers.
- •
As the angle of attack increases, the area of flow separation expands.
- •
Separation bubble is presented at the case of TI = 0.20% and Re = 2.0 × 105.
