Scaling in laminar natural convection in laterally heated cavities: is turbulence essential in the classical scaling of heat transfer?

Abstract

We analyze heat transfer and flow properties in laminar natural convection driven by a horizontal temperature gradient in a closed cavity and propose that for the classical scaling of heat transfer turbulence does not play a decisive role. Direct numerical simulations were performed with the Rayleigh number (Ra) from 1 to 10(8) and the Prandtl number Pr = 0… (More)
