Whole field measurements to identify the critical Rayleigh number for the onset of natural convection in top open cavity

Experimental heat transfer, 2020
We report the results of interferometry-based experiments to identify the onset of natural convection in an air-filled top open cavity. Transition from no flow to the onset of fluid motion was identified as the sharp change in local heat transfer ...

Heat transport in high-Rayleigh-number convection.

Physical Review A, 1990
The heat flux (Nusselt number) as a function of Rayleigh number, ${\mathit{N}}_{\mathrm{Nu}}$\ensuremath{\approxeq}0.3${\mathit{N}}_{\mathrm{Ra}}^{2/7}$, is deduced from the presence of a mean flow and the nesting of the thermal boundary layer within the viscous one.

Small Atwood number Rayleigh–Taylor experiments

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
Consideration is given to small Atwood number (non-dimensional density difference) experiments to investigate mixing driven by Rayleigh–Taylor (R–T) instability. The past 20 years have seen the development of novel experiments to investigate R–T mixing and, simultaneously, the advent of high-fidelity diagnostics. Indeed, the developments of experiments

High Rayleigh number β-convection

Geophysical & Astrophysical Fluid Dynamics, 1993
Abstract High resolution numerical simulations of thermal convection in a rapidly rotating channel with gravity perpendicular to the rotation vector are described. The convecting columns are subject to a β-effect resulting from topographic vortex stretching.
