Transition to turbulence in the rotating-disk boundary-layer flow with stationary vortices
This paper proposes a resolution to the conundrum of the roles of convective and absolute instability in transition of the rotating-disk boundary layer. It also draws some comparison with swept-wing

Direct numerical simulations of the rotating-disk boundary-layer flow
This thesis deals with the instabilities of the incompressible boundary-layer flow that is induced by a disk rotating in otherwise still fluid. The results presented are mostly limited to linear in
Studies of the rotating-disk boundary-layer flow
The rotating-disk boundary layer is not only a simpler model for the study of cross-flow instability than swept-wing boundary layers but also a useful simplification of many industrial-flow applica
Turbulent Flow Due to a Rotating Disk
The results of an experiment, conducted to determine the turbulent structure of the flow due to a rotating disk, are presented. Mean velocities, turbulent intensities, and one Reynolds stress
Exploratory investigation of laminar-boundary-layer oscillations on a rotating disk
Sinusoidal waves excited by random disturbances have been observed in the laminar boundary layer of a rotating disk at Reynolds numbers in a narrow range below the Reynolds number of transition.
Secondary instability in rotating disk flow
Primary instability of the 3D boundary layer on a rotating disk introduces periodic modulation of the mean flow in the form of stationary crossflow vortices. We study the stability of this modulated

This paper is concerned with the theoretical behaviour of the boundary-layer flow over a disk rotating in otherwise still fluid. The flow is excited impulsively at a certain radius at time t = 0.
Study on boundary layer transition of a rotating disk
SummaryBehaviour of spiral vortices being generated in transition regime of a disk rotating in otherwise undisturbed fluid is experimentally studied in detail. Through visualizations of the
Turbulent boundary layer on a rotating disk in infinite quiescent fluid
An experimental study of the turbulent flow due to a rotating disk in an infinite quiescent fluid was conducted. Using a single normal- and an inclined-type hot wire, the mean velocity distributions
On the stability of three-dimensional boundary layers with application to the flow due to a rotating disk
A phenomenon of boundary-layer instability is discussed from the theoretical and experimental points of view. The china-clay evaporation technique shows streaks on the surface, denoting a vortex
On the global nonlinear instability of the rotating-disk flow over a finite domain
Direct numerical simulations based on the incompressible nonlinear Navier–Stokes equations of the flow over the surface of a rotating disk have been conducted. An impulsive disturbance was introduced
