A critical point for bifurcation cascades and featureless turbulence
Jacopo Canton, Enrico Rinaldi, Ramis Örlü +1
In this Letter we show that a bifurcation cascade and fully sustained turbulence can share the phase space of a fluid flow system, resulting in the presence of competing stable att…

Revisiting the amplitude modulation in wall-bounded turbulence: towards a robust definition
E. Dogan, R. Örlü, D. Gatti +2
The present study revisits the amplitude modulation phenomenon, specifically for the robustness in its quantification. To achieve this, a well-resolved large-eddy simulation (LES)…

The three-dimensional structure of swirl-switching in bent pipe flow
Lorenz Hufnagel, Jacopo Canton, Ramis Oerlue +3
Swirl-switching is a low-frequency oscillatory phenomenon which affects the Dean vortices in bent pipes and may cause fatigue in piping systems. Despite thirty years worth of resea…
