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…

Mathematically established chaos and forecast of statistics with recurrent patterns in Taylor-Couette flow
Baoying Wang, Roger Ayats, Kengo Deguchi +2
The transition to chaos in the subcritical regime of counter-rotating Taylor-Couette flow is investigated using a minimal periodic domain capable of sustaining coherent structures.…

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…
