Abstract

In order to study the measurement of boundary layer transition and the processing method of fluctuation pressure signal in airfoil dynamic experiment, an airfoil wind tunnel test is carried out to analyze the characteristics of boundary layer fluctuation pressure and the determination method of transition under different oscillation frequencies. Result shows that the transition determination method based on RMS in static experiment also applies to the dynamic, and the RMS value of dynamic experiment is greater than that of static experiment under the same state, and also has multiple peaks. The first peak position has a strong transition characteristic which can be used to determine transition position. Besides, the dynamic experiment has an earlier transition position than that of static.

Key words： wind tunnel test; dynamic experiment; boundary layer transition; fluctuating pressure
