| Abstract: | The tangentially blowing sidewall boundary layer control system for a 2 D test section of NF 3 wind tunnel and the relevant model experiment method are presented briefly in this paper. The effects of different blowing coefficients on the efficiency of sidewall boundary layer control and on the experiment results for an airfoil with relative thickness 7% are given. This work shows that the control system will improve the sidewall boundary layer flow and give an improved 2 D flow characteristics of the test section. |

| Keywords: | two dimensional wind tunnel airfoil sidewall interfere blowing control system. |
