Abstract
Hot wire measurements in an axisymmetric jet are presented. A resonant subharmonic interaction between the two axisymmetric travelling waves was induced in the shear layer of the jet by controlled sinusoidal perturbations with two frequencies separated by one octave. The phase averaging technique was applied to assess the evolution of the coherent waves. By Fourier decomposing the phase averaged data it was possible to obtain the magnitude as well as the phase of the measured signal.
