Emergence of chaos and fractality in the basin boundary of subcritical shear flow
Baoying Wang, Roger Ayats, Kengo Deguchi +2
From a dynamical systems perspective of subcritical transition in shear flows, the basin boundary separating the laminar and turbulent attractors, along with the edge state that go…

Feigenbaum universality in subcritical Taylor-Couette flow
Baoying Wang, Roger Ayats, Kengo Deguchi +2
Feigenbaum universality is shown to occur in subcritical shear flows. Our testing ground is the counter-rotation regime of the Taylor-Couette flow, where numerical calculations are…

From directed percolation to patterned turbulence
Roger Ayats, Lukasz Klotz, Björn Hof
The transition to turbulence is characterized by an abrupt loss of order and predictability, featuring the intermittent proliferation and decay of localized turbulent structures. E…
