Abstract
In this paper a low dimensional dynamical system is used to model the local
evolution of a disturbance superimposed on a basic shear flow. In particular,
non-linear interactions between planar waves and oblique waves which travel
phase-locked in the far wake of a cylinder are simulated. At this aim a low-
dimensional dynamical system is derived by imposing the respect of a non-
linear truncation condition together with those phase-locked condition
experimentally observed. The numerical results are compared with some recent
experimental results obtained analysing the dynamics of a cylinder far wake.
Different experimental conditions were modelled by dynamical systems defined
by one or more coupled triadic systems. The energy spectral dis
