Journal ArticleDOI
Boundary layer control of rotating convection systems
TL;DR: In this paper, it was shown that the transition from rotationally dominated to non-rotating heat transfer is not determined by the global force balance, but by the relative thickness of the thermal and Ekman boundary layers.
Journal ArticleDOI
Heat transfer by rapidly rotating Rayleigh–Bénard convection
TL;DR: In this paper, an exact scaling law for heat transfer by geostrophic convection, by considering the stability of the thermal boundary layers, where, and are the Nusselt, Rayleigh and Ekman numbers, respectively, and is the critical Rayleigh number for the onset of convection.
Journal ArticleDOI
Approaching the asymptotic regime of rapidly rotating convection: boundary layers versus interior dynamics.
Stephan Stellmach,Lischper M,Keith Julien,Geoffrey M. Vasil,Jonathan S. Cheng,Adolfo Ribeiro,E. M. King,Jonathan M. Aurnou +7 more
TL;DR: It is found that multiple well-defined dynamical regimes exist in rapidly rotating convection systems, and the heat transfer jumps from values broadly compatible with the asymptotic theory to states of strongly increased heat transfer, in good quantitative agreement with no-slip DNS andcompatible with the experimental data.
Journal ArticleDOI
Rotating convective turbulence in Earth and planetary cores
Jonathan M. Aurnou,Michael A. Calkins,Jonathan S. Cheng,Keith Julien,E.M. King,David Nieves,Krista M. Soderlund,Stephan Stellmach +7 more
TL;DR: In this paper, a closely coupled suite of advanced asymptotically-reduced theoretical models, efficient Cartesian direct numerical simulations (DNS) and laboratory experiments are presented.
Journal ArticleDOI
Numerically Determined Transport Laws for Fingering ("Thermohaline") Convection in Astrophysics
TL;DR: In this paper, the authors present the first three-dimensional simulations of fingering convection performed at parameter values approaching those relevant for astrophysics, revealing the existence of simple asymptotic scaling laws for turbulent heat and compositional transport.
