Journal ArticleDOI
Laboratory-numerical models of rapidly rotating convection in planetary cores
Jonathan S. Cheng,Stephan Stellmach,Adolfo Ribeiro,A. M. Grannan,E. M. King,Jonathan M. Aurnou +5 more
TL;DR: Cheng et al. as discussed by the authors investigated the behavioural regimes of rapidly rotating convection in high-latitude planetary core-style settings and found that coherent, axial columns have a relatively narrow range of stability.
Journal ArticleDOI
Jump rope vortex in liquid metal convection.
TL;DR: Brown et al. as discussed by the authors showed that large-scale circulations in turbulent convective systems take the form of a jump rope vortex, a strongly 3D mode that periodically orbits around the tank following a motion much like a jump-robin on a playground.
Journal ArticleDOI
Rotating thermal convection in liquid gallium: multi-modal flow, absent steady columns
TL;DR: In this paper, a cylinder of aspect ratio with liquid gallium as the working fluid was used to study the dynamics of low-number convective flows in low-volatile fluids.
Journal ArticleDOI
Libration-driven flows in ellipsoidal shells
Daphné Lemasquerier,Daphné Lemasquerier,A. M. Grannan,Jérémie Vidal,David Cébron,Benjamin Favier,M. Le Bars,Jonathan M. Aurnou +7 more
TL;DR: In this article, the persistence of LDEI in the more geophysically relevant ellipsoidal shell geometries is addressed for the first time, and the results show that the generated turbulence can be latitudinally inhomogeneous.
Journal ArticleDOI
Generation and maintenance of bulk turbulence by libration-driven elliptical instability
TL;DR: In this paper, the authors present a combination of direct numerical simulations and laboratory experiments, modeling this geophysically relevant mechanical forcing, and investigate the fluid motions inside a longitudinally librating ellipsoidal container filled with an incompressible fluid.
