Analysis and modeling of localized invariant solutions in pipe flow

Analysis and modeling of localized invariant solutions in pipe flow
Baofang Song, Paul Ritter, Bruno Eckhardt, Marc Avila, Stefan Zammert
In transitional pipe flow, isolated turbulent spots carry substantial pressure and velocity fluctuations as they travel along the pipe. A model is proposed that links the propagation speed of such spots with the exact coherent solutions to their spatial localization rate.
