Orthogonal decomposition of the axisymmetric jet mixing layer including azimuthal dependence.

In the current work experiments were performed in the mixing region of an axisymmetric turbulent jet at x/D = 3. These experiments involve adding the azimuthal variation to the problem reported where the decomposition was utilized for variations in time and in the radial direction. The motivation for these additional experiments is to shed further light on the turbulent structure in the jet mixing layer and to examine the effect on the orthogonal decompositon of adding a dimension to the problem.
