| Abstract: | A controllable spire device has been developed for boundary layer simulation in wind tunnel.The feasibility and control program of the mechanism have been investigated.Experimental results have demonstrated the mechanical vibration of the spires in a certain frequency will enhance simulated turbulence energy around corresponding frequency point,and increase the integral length of turbulence. |

| Keywords: | active simulation boundary layer wind tunnel power density spectra integral length of turbulence |
