Structures of various spanwise lengthscales are highlighted by means of short time averaged flowfield and spatial Fourier transforms. The individual influences of each of these modulations on the

This phenomenon is reviewed and analyzed, by evaluating the results of various experiments; in particular results in the case of a shock reflection are presented. It appears that the frequency of the fluctuations produced by the shock motion are much lower than the characteristic frequencies of turbulence in the incoming
