Rayleigh–Bénard convection in rotating spherical shells can be considered as a simplified analogue of many astrophysical and geophysical fluid flows. Here, we use three-dimensional direct numerical simulations to study this physical process. We construct a dataset of more than 200 numerical models that cover a broad parameter range with Ekman numbers spanning $3\times 10^{-7}\leqslant E\leqslant 10^{-1}$ , Rayleigh numbers within the range $10^{3}<Ra<2\times 10^{10}$ and a Prandtl number of… 
Scaling behaviour in spherical shell rotating convection with fixed-flux thermal boundary conditions
Bottom-heated convection in rotating spherical shells provides a simple analogue for many astrophysical and geophysical fluid systems. We construct a database of 74 three-dimensional numerical
Heat transfer in rapidly rotating convection with heterogeneous thermal boundary conditions
Convection in the metallic cores of terrestrial planets is likely to be subjected to lateral variations in heat flux through the outer boundary imposed by creeping flow in the overlying silicate
Laboratory exploration of heat transfer regimes in rapidly rotating turbulent convection
We report heat transfer and temperature profile measurements in laboratory experiments of rapidly rotating convection in water under intense thermal forcing (Rayleigh number $Ra$ as high as $\sim
Experimental study of the convection in a rotating tangent cylinder
This paper experimentally investigates the convection in a rapidly rotating tangent cylinder (TC), for Ekman numbers down to $E=3.36\times 10^{-6}$ . The apparatus consists of a hemispherical fluid
Prograde, retrograde, and oscillatory modes in rotating Rayleigh–Bénard convection
Rotating Rayleigh–Bénard convection is typified by a variety of regimes with very distinct flow morphologies that originate from several instability mechanisms. Here we present results from direct
Rotating thermal convection in liquid gallium: multi-modal flow, absent steady columns
Earth’s magnetic field is generated by convective motions in its liquid metal core. In this fluid, the heat diffuses significantly more than momentum, and thus the Prandtl number $Pr$ is well below
Thermal convection in rotating spherical shells: Temperature-dependent internal heat generation using the example of triple- α burning in neutron stars
We present an exhaustive study of Boussinesq thermal convection including a temperature-dependent internal heating source, based on numerical three-dimensional simulations. The temperature dependence
Scaling Laws in Rayleigh‐Bénard Convection
The heat transfer scaling theories for Rayleigh‐Bénard convection (RBC) are reviewed and discussed for configurations with and without rotation and magnetic fields. Scaling laws are a useful tool in
Prandtl-number Effects in High-Rayleigh-number Spherical Convection
Convection is the predominant mechanism by which energy and angular momentum are transported in the outer portion of the Sun. The resulting overturning motions are also the primary energy source for
A heuristic framework for next-generation models of geostrophic convective turbulence
This study combines asymptotic predictions, laboratory and numerical results, and experimental constraints to build a heuristic framework for cross-comparison between a broad range of rotating convection studies, demonstrating that laboratory studies may soon be able to characterize geophysically-relevant flow regimes.


Turbulent Rayleigh–Bénard convection in spherical shells
We simulate numerically Boussinesq convection in non-rotating spherical shells for a fluid with a Prandtl number of unity and for Rayleigh numbers up to $10^{9}$ . In this geometry, curvature and
Scaling behaviour in Rayleigh–Bénard convection with and without rotation

Thermal convection in a rotating spherical shell with free-slip boundaries can excite a dominant mean zonal flow in the form of differentially rotating cylinders concentric to the principal rotation
Heat transfer by rapidly rotating Rayleigh–Bénard convection
Abstract Turbulent, rapidly rotating convection has been of interest for decades, yet there exists no generally accepted scaling law for heat transfer behaviour in this system. Here, we develop an
