A new flow control approach called split blade is applied on the S809 airfoil in the present study.
S809 airfoil was investigated experimentally and numerically with different operating conditions including cascade without control, cascade with slots that generate jets with AOAs of 0 degrees, 10 degrees, 15 degrees and 20 degrees.
Good agreement was obtained between the comparison of the experimental and numerical results.
The results show that the separation area increases with increase of the AOA and the large separation area appears on the airfoil suction surface at AOA equal to 20 degrees.
Numerical results show that the control method has little negative influence on the airfoil performance at small AOAs.
Smaller vortices are filled with the large separated area which is divided by the jet generated by split when the AOA is 20 degrees.
The analysis on the lift coefficient and drag coefficient shows that the flow is improved with the control.
The lift coefficient and drag coefficient do not change in the comparison between the cases before and after control when AOA is 0 degrees and 10 degrees.
However, the lift coefficient increases and drag coefficient decreases when AOA is 15 degrees and 20 degrees.
