TODO - The structure of turbulence in a reduced model of turbulence (RNL) is
analyzed by means of a Proper Orthogonal Decomposition (POD modes). POD
analysis was carried out on two different components of the flow, the
roll/streak and the perturbation structure. The POD structure in both
RNL and direct numerical simulations (DNS) is similar and this
correspondence suggests that the dynamics retained in RNL are the
essential dynamical ingredients underlying the self-sustaining mechanism
of the turbulent state.
