Quantifying near-wall coherent structures in turbulent convection

ORAL

Abstract

We present planforms of line plumes formed on horizontal surfaces in turbulent convection, along with the length of near- wall line plumes measured from these planforms, in a six decade range of Rayleigh numbers ($10^5
