Low-dimensional Models for Subcritical Turbulence in Channel Flow - A Model Hierarchy Built on Production, Transfer and Dissipation of Turbulent Kinetic Energy

Low-dimensional Models for Subcritical Turbulence in Channel Flow - A Model Hierarchy Built on Production, Transfer and Dissipation of Turbulent Kinetic Energy

The onset of turbulence in channel flow can be observed way below the actual linear instability of the laminar profile \parencite{Carlson1982, Orszag1971}. In this subcritical regime, suitably chosen three-dimensional perturbations lead to transiently growing turbulence, showing a spatio-temporal...
