Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

Experiments and numerical simulations have shown that turbulence in transitional wall-
bounded shear flows frequently takes the form of long oblique bands if the domains are …

Turbulent-laminar patterns near transition are simulated in plane Couette flow using an
extension of the minimal-flow-unit methodology. Computational domains are of minimal size …

Chimera states consisting of domains of coherently and incoherently oscillating identical
oscillators with nonlocal coupling are studied. These states usually coexist with the fully …

We study the large-scale motions in turbulent plane Couette flows at moderate friction
Reynolds number up to length of the domain. The presence of these very long structures is …

We examine the onset of turbulence in Waleffe flow–the planar shear flow between stress-
free boundaries driven by a sinusoidal body force. By truncating the wall-normal …

The flow between concentric cylinders is routinely used in soft matter studies. In many cases,
the purpose of the setup is rheometric: the idea is to relate macroscopic changes in material …

This paper provides discussion and prescription about stability and transport in the Taylor–
Couette experiment, a rotating shear flow with shear perpendicular to the rotation axis. Such …

When fluid flows through a channel, pipe, or duct, there are two basic forms of motion:
smooth laminar motion and complex turbulent motion. The discontinuous transition between …

A turbulent–laminar banded pattern in plane Couette flow is studied numerically. This
pattern is statistically steady, is oriented obliquely to the streamwise direction, and has a …
