The progress in our understanding of several aspects of turbulent Rayleigh-Bénard
convection is reviewed. The focus is on the question of how the Nusselt number and the …

A systematic theory for the scaling of the Nusselt number Nu and of the Reynolds number
Re in strong Rayleigh–Bénard convection is suggested and shown to be compatible with …

Turbulent Boussinesq convection under the influence of rapid rotation (ie with comparable
characteristic rotation and convection timescales) is studied. The transition to turbulence …

Abstract Properties of the mean wind in thermal convection, especially the abrupt reversal of
its direction at high Rayleigh numbers, are studied. Measurements made in a closed …

Turbulent rotating convection controls many observed features of stars and planets, such as
magnetic fields, atmospheric jets and emitted heat flux patterns,,,,,. It has long been argued …

Turbulent, rapidly rotating convection has been of interest for decades, yet there exists no
generally accepted scaling law for heat transfer behaviour in this system. Here, we develop …

A systematic study of large-scale velocity structures in turbulent thermal convection is carried
out in three different aspect-ratio cells filled with water. Laser Doppler velocimetry is used to …

We experimentally study the temperature and velocity fields in high Rayleigh number (Ra)
convection by making local measurements as a function of distance from the boundary in a …

A novel convection experiment is conducted in a cell with rough upper and lower surfaces.
The measured heat transport in the rough cell is found to be increased by more than 76 …

We studied thermal turbulence in a low Prandtl number, Pr, fluid using liquid Hg (Pr= 0.024).
For Rayleigh numbers (10 6< Ra< 10 8), the histogram of temperature fluctuations at the …
