Laminar-turbulent coexistence in annular Couette flow
Kohei Kunii, Takahiro Ishida, Yohann Duguet +1
Annular Couette flow is the flow between two coaxial cylinders driven by the axial translation of the inner cylinder. It is investigated using direct numerical simulation in long d…

Turbulent bifurcations in intermittent shear flows: from puffs to oblique stripes
Takahiro Ishida, Yohann Duguet, Takahiro Tsukahara
Localised turbulent structures such as puffs or oblique stripes are building blocks of the intermittency regimes in subcritical wall-bounded shear flows. These turbulent structures…
