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…
