Abstract: Abstract We prove a new rigorous bound for the mean convective heat transport $\langle w T \rangle$, where $w$ and $T$ are the non-dimensional vertical velocity and temperature, in internally heated convection between an insulating… read more here.

Abstract: Abstract We study convection in a volumetrically heated fluid which is cooled from both plates and is under rotation through the use of direct numerical simulations. The onset of convection matches similar systems and predictions… read more here.

DOI: 10.1063/5.0209505
Abstract: We prove new bounds on the heat flux out of the bottom boundary, FB, for a fluid at infinite Prandtl number, heated internally between isothermal parallel plates, under two kinematic boundary conditions. In uniform internally… read more here.

DOI: 10.1093/mnras/staf1131
Abstract: Models of astrophysical convection, such as mixing length theory, typically assume that the heat transport is independent of microphysical diffusivities. Such ‘diffusion-free’ behaviour is, however, not observed in numerical simulations employing standard fixed-flux or fixed-temperature… read more here.
