• A critical-layer framework for turbulent pipe flow (2010, methodology): “Cossu et al. (2009) performed a similar analysis in a turbulent boundary layer, modelling it as a parallel flow. The realization that turbulent wall flows can be linearly stable followed the work of Reynolds & Tiederman (1967), who demonstrated this for turbulent channel flow.”
