Spatiotemporal intermittency in the torsional Couette flow between a rotating and a stationary disk
Physics of Fluids, 2002This work is devoted to the experimental study of the transition to turbulence of a flow confined in a narrow gap between a rotating and a stationary disk. When the fluid layer thickness is of the same order of magnitude as the boundary layer depths, the azimuthal velocity axial gradient is nearly constant and this rotating disk flow tends to be a ...

Laminar Torsional Couette Flow Over a Wavy Disk
Journal of Fluids Engineering, 2023Abstract A parametric study of laminar torsional Couette flow between a rotating flat disk and a stationary wavy disk is conducted using computer simulations. The waviness of the stationary disk, characterized by the parameter wave slope (WS), is increased across four cases to evaluate its influence.

Abstract We proposed a HiGee fundamentally different from the present-day HiGees. A separated two-phase flow prevails in the proposed HiGee in contrast to an interpenetrated flow in other HiGees. It comprises of a rotating disc placed in the middle of two stationary discs which are enclosed in a casing.

Defect turbulence in a spiral wave pattern in the torsional Couette flow
Physical Review E, 2004Our experimental study is devoted to the transition to defect turbulence of a periodic spiral wave pattern occurring in the flow between a rotating and a stationary disk. As the rotation rate Omega of the disk is increased, the radial phase velocity of the waves changes its sign: The waves that propagate first outward on average, then become stationary
