Inverse cascades of kinetic energy and thermal variance in three-dimensional horizontally extended turbulent convection

Philipp P. Vieweg, Janet D. Scheel, Rodion Stepanov +1

Inverse cascades of kinetic energy and thermal variance in the subset of vertically homogeneous modes in spectral space are found to cause a slow aggregation to a pair of convectiv…

Transitional boundary layers in low-Prandtl-number convection

Jörg Schumacher, Vinodh Bandaru, Ambrish Pandey +1

The boundary layer structure of the velocity and temperature fields in turbulent Rayleigh-Benard flows in closed cylindrical cells of unit aspect ratio is revisited from a transiti…

Extreme dissipation event due to plume collision in a turbulent convection cell

Joerg Schumacher, Janet D. Scheel

An extreme dissipation event in the bulk of a closed three-dimensional turbulent convection cell is found to be correlated with a strong reduction of the large-scale circulation fl…

Global and local statistics in turbulent convection at low Prandtl numbers

Janet D. Scheel, Joerg Schumacher

Statistical properties of turbulent Rayleigh-Benard convection at low Prandtl numbers (Pr), which are typical for liquid metals such as mercury, gallium or liquid sodium, are inves…

Local boundary layer scales in turbulent Rayleigh-Benard convection

Janet D. Scheel, Joerg Schumacher

We compute fully local boundary layer scales in three-dimensional turbulent Rayleigh-Benard convection. These scales are directly connected to the highly intermittent fluctuations…
