Three-dimensional velocity gradient statistics in a mesoscale convection laboratory experiment
Prafulla P. Shevkar, Roshan J. Samuel, Christian Cierpka +1
We present three-dimensional velocity gradient statistics from Rayleigh--Bénard convection experiments in a horizontally extended cell of aspect ratio 25, a paradigm for mesoscale…

Flux scaling in Rayleigh Bénard convection: a local boundary layer analysis
Prafulla P. Shevkar, Baburaj A. Puthenveettil
We study the effect of shear due to the large scale flow (LSF) on the heat flux in Rayleigh B'enard convection for a range of near-plate Rayleigh numbers $8\times 10^7 \leq Ra_w \l…
