Invariant solutions in a channel flow using a minimal restricted nonlinear model

Invariant solutions in a channel flow using a minimal restricted nonlinear model

A restricted non linear (RNL) system with a single Fourier mode for the perturbation in the streamwise direction is coupled with a shooting method to track exact coherent states in a plane channel flow. The fundamental importance of the streak/roll interaction onto the space/time dynamics of these invariant solutions is clearly enlightened through investigations of rolls, streaks and perturbations time evolutions.
