Zusammenfassung:
Experimental results show that the streamwise location of transition in a flat plate boundary layer can be monitored by the measurement of surface pressure fluctuations. Furthermore it is shown that these pressure fluctuations can be used to maintain transition at a desired location further downstream via a control system which regulates boundary layer suction through a porous titanium sheet. The integral controller in the system shows great abilities to give to the system a fast and stable response in the presence of external disturbances. The prediction of stability made from the identification of the plant is in good agreement with experimental results.
