Repeller or Attractor? Selecting the Dynamical Model for the Onset of Turbulence in Pipe Flow

The collapse of turbulence, observable in shear flows at low Reynolds numbers, raises the question if turbulence is generically of a transient nature or becomes sustained at some critical point. Recent data have led to conflicting views with the majority of studies supporting the model of turbulence turning into an attracting state. Here we...
