Prandtl and Rayleigh number dependence of heat transport in high Rayleigh number thermal convection [PDF]
Journal of Fluid Mechanics, 2011 AbstractResults from direct numerical simulation for three-dimensional Rayleigh–Bénard convection in samples of aspect ratio $\Gamma = 0. 23$ and $\Gamma = 1/ 2$ up to Rayleigh number $\mathit{Ra}= 2\ensuremath{\times} 1{0}^{12} $ are presented. The broad range of Prandtl numbers $0. 5\lt \mathit{Pr}\lt 10$ is considered.

Fluids, 2023 In rotating Rayleigh–Bénard problems, convection with traveling waves may occur near the sidewalls. The Rayleigh number, Taylor number and Prandtl number are involved in this phenomenon, and the convection mode is determined depending on their values. We

A boundary-layer analysis of Rayleigh-Bénard convection at large Rayleigh number
Journal of Fluid Mechanics, 1987 A boundary-layer analysis is presented for the two-dimensional nonlinear convection of an infinite-Prandtl-number fluid in a rectangular enclosure, in the limit of large Rayleigh numbers. Particular emphasis is given to the analysis of the periodic boundary layers, and on the removal of the singularities that appear near the corners of the cell.

Asymptotics of the number of Rayleigh resonances [PDF]
Mathematische Annalen, 1997 Resonances associated to the Neumann problem in linear elasticity are studied. It is well-known that for this problem there are surface waves called Rayleigh waves moving with a speed \(c_R>0\) strictly less than the two speeds in the exterior domain. For a class of obstacles including strictly convex ones the following asymptotic for the number, \(N(r)
