Convection driven by internal heat sources and sinks: heat transport beyond the mixing-length or "ultimate" scaling regime
B. Miquel, S. Lepot, V. Bouillaut +1
Thermal convection driven by internal heat sources and sinks was recently shown experimentally to exhibit the mixing-length, or "ultimate", scaling-regime: the Nusselt number …

Transition to the ultimate regime in a radiatively driven convection experiment
V. Bouillaut, S. Lepot, S. Aumaître +1
We report on the transition between two regimes of heat transport in a radiatively driven convection experiment, where a fluid gets heated up within a tunable heating length …

On the role of the Prandtl number in convection driven by heat sources and sinks
Benjamin Miquel, Vincent Bouillaut, Sebastien Aumaitre +1
We report on a numerical study of turbulent convection driven by a combination of internal heat sources and sinks. Motivated by a recent experimental realisation (Lepot et al. 2018…
