Conference paper


LIF measurements of density fluctuations in a turbulent supersonic free shear layer producedin a Ludwieg tube’s asymmetric nozzle provide evidence of turbulent shocklets and the underlying turbulent burst dynamics. Correlations of shocklet phenomena with changes in chaotic dimension motivate a quasi-one dimensional approximation for an estimator of shocklet properties which makes predictions consistent with the measurements reported and has implications for shocklet observations in other systems.
