We report a laboratory study of the transport of angular momentum by a turbulent flow of an electrically conducting fluid confined in a thin disk. When the electromagnetic force applied to the liquid metal is large enough, the corresponding volume injection of angular momentum produces a turbulent flow characterized by a time-averaged Keplerian rotation rate Ω[over ¯]∼r^{-3/2}. Two contributions to the local angular momentum transport are identified: one from the poloidal recirculation induced…

Liquid Metal Experiment Mimics Accretion Disks

A strophysical disks are ubiquitous objects in the cosmic landscape: we observe them aroundmatter-gobbling black holes and planet-forming stellar systems. The gas and dust in these disks slowly drift



Angular momentum transport and turbulence in laboratory models of Keplerian flows

We present angular momentum transport (torque) measurements in two recent experimental studies of the turbulent flow between independently rotating cylinders. In addition to these studies, we

Turbulence in electromagnetically driven Keplerian flows

Abstract The flow of an electrically conducting fluid in a thin disc under the action of an azimuthal Lorentz force is studied experimentally. At small forcing, the Lorentz force is balanced by

Stability of quasi-Keplerian shear flow in a laboratory experiment

Subcritical transition to turbulence has been proposed as a source of turbulent viscosity required for the associated angular momentum transport for fast accretion in Keplerian disks. Previously

Hydrodynamic turbulence cannot transport angular momentum effectively in astrophysical disks

A laboratory experiment is reported, demonstrating that non-magnetic quasi-keplerian flows at Reynolds numbers up to millions are essentially steady, indirectly support the magnetorotational instability as the likely cause of turbulence, even in cool disks.

Angular momentum transport in accretion disks: a hydrodynamical perspective

The radial transport of angular momentum in accretion disk is a fundamental process in the universe. It governs the dynamical evolution of accretion disks and has implications for various issues

Boundary-layer turbulence in experiments on quasi-Keplerian flows

Most flows in nature and engineering are turbulent because of their large velocities and spatial scales. Laboratory experiments on rotating quasi-Keplerian flows, for which the angular velocity

Rotating flow in which the angular velocity decreases outward while the angular momentum increases is known as ‘quasi-Keplerian’. Despite the general tendency of shear flow to break down into

Focus on new perspectives in high-Rayleigh-number turbulent convection

Thermal convection in a gravitational field is the source of most large-scale flows on Earth, planets and stars. It is also used to heat houses or to cool passively with metal vanes, as for example
