Vibration-induced boundary-layer destabilization achieves massive heat-transport enhancement

BF Wang, Q Zhou, C Sun - Science advances, 2020 - science.org
Thermal turbulence is well known as a potent means to convey heat across space by a
moving fluid. The existence of the boundary layers near the plates, however, bottlenecks its …

Connections between nonrotating, slowly rotating, and rapidly rotating turbulent convection transport scalings

JM Aurnou, S Horn, K Julien - Physical Review Research, 2020 - APS
In this paper, we investigate and develop scaling laws as a function of external
nondimensional control parameters for heat and momentum transport for nonrotating, slowly …

Rotation suppresses giant-scale solar convection

GM Vasil, K Julien… - Proceedings of the …, 2021 - National Acad Sciences
The observational absence of giant convection cells near the Sun's outer surface is a long-

Convective outgassing efficiency in planetary magma oceans: insights from computational fluid dynamics

A Salvador, H Samuel - Icarus, 2023 - Elsevier
Planetary atmospheres are commonly thought to result from the efficient outgassing of
cooling magma oceans. During this stage, vigorous convective motions in the molten interior …
