Authors performed analysis by the Proper Orthogonal Decomposition procedure of two air jets, one of them naturally evolving and the other with excited two helical intsanilities in the shear leyer surriunding the core. Several modes of cogherent structures were identified, differing significantly in the case with the excitation
