Abstract:
By applying the dynamic schlilieren photon correlation technique to a two dimensional separated supersonic, chear layar, the convection velocity of large eddies inside the shear layer and the frequency o! the self-sustaining oscillation of the shear layer induced by the shedding of large eddies have been obtained The distribution of the turbulence in-tenaity inside the chear layer can also be estimated.It has been observed that the large eddies in a high sptcd shear layer posses; some special features.It is shown tha t the method has its promising potential in the measurement of high speed complex flows.
Key words: schlieren, correlation techniques, supersoic flow, turbulent shear flow
