Shock-Tracking Procedure for Studying Screech-Induced Oscillations

Shock-Tracking Procedure for Studying Screech-Induced Oscillations

Andre et al discuss screech-induced oscillations. Oscillation frequency and amplitude are examined by means of high-speed schlieren images and simultaneous near-field acoustic recordings. A procedure for shock tracking is developed and applied on two different screech modes.
