Vertical natural convection: application of the unifying theory of thermal convection [PDF]
J. Fluid Mech. 764 (2015) 349-361, 2018 Results from direct numerical simulations of vertical natural convection at Rayleigh numbers $1.0\times 10^5$-$1.0\times 10^9$ and Prandtl number $0.709$ support a generalised applicability of the Grossmann-Lohse (GL) theory, which was originally developed for horizontal natural (Rayleigh-B{\'e}nard) convection.
