Drag reduction in pipe flow by optimal forcing
Ashley P. Willis, Yongyun Hwang, Carlo Cossu
In most settings, from international pipelines to home water supplies, the drag caused by turbulence raises pumping costs many times higher than if the flow were laminar. Drag redu…

Coherent structures in fully-developed pipe turbulence
A. P. Willis, Y. Hwang, C. Cossu
A turbulent mean profile for pipe flow is prescribed which closely matches experimental observations. The nature of perturbations superimposed upon this profile is then considered.…

On the transient nature of localized pipe flow turbulence
M. Avila, A. P. Willis, B. Hof
The onset of shear flow turbulence is characterized by turbulent patches bounded by regions of laminar flow. At low Reynolds numbers localized turbulence relaminarises, raising the…
