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…

Dynamics of collapse of free-surface bubbles: effects of gravity and viscosity
Sangeeth Krishnan, Baburaj A. Puthenveettil, Emil J. Hopfinger
The rupture of the thin film at the top of a bubble floating at a liquid-gas interface leads to the axisymmetric collapse of the bubble cavity. We present scaling laws for such a c…
