Effects of a subadiabatic layer on convection and dynamos in spherical wedge simulations [PDF]
Geophys. Astrophys. Fluid Dyn. 113, 149-183 (2020), 2018 We consider the effect of a subadiabatic layer at the base of the convection zone on convection itself and the associated large-scale dynamos in spherical wedge geometry. We use a heat conduction prescription based on the Kramers opacity law which allows the depth of the convection zone to dynamically adapt to changes in the physical characteristics ...

Advanced Functional Materials, EarlyView.This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...

Enhanced visualisation of complex thermofluid data: Vertical and horizontal combined convection and microscale heat transfer cases [PDF]
, 2000 Copyright @ 2000 UITIn general, convective heat transfer is an 'n-dimensional' problem where n is well in excess of 3 for steady flows. Traditionally, the method of dimensional analysis results in a small number of dimensionless groups.

The Spectral Amplitude of Stellar Convection and its Scaling in the High-Rayleigh-Number Regime [PDF]
, 2015 Convection plays a central role in the dynamics of any stellar interior, and yet its operation remains largely-hidden from direct observation. As a result, much of our understanding concerning stellar convection necessarily derives from theoretical and computational models. The Sun is, however, exceptional in that regard.

Penetrative Convection in Partly Stratified Rapidly Rotating Spherical Shells [PDF]
Front. Earth Sci. 6:189 (2018), 2018 Celestial objects host interfaces between convective and stable stratified interior regions. The interaction between both, e.g., the transfer of heat, mass, or angular momentum depends on whether and how flows penetrate into the stable layer. Powered from the unstable, convective regions, radial flows can pierce into the stable region depending on ...
