Heat transfer and large scale dynamics in turbulent Rayleigh-Bénard convection [PDF]
, 2009 The progress in our understanding of several aspects of turbulent Rayleigh-Bénard convection is reviewed. The focus is on the question of how the Nusselt number and the Reynolds number depend on the Rayleigh number Ra and the Prandtl number Pr, and on ...

Comptes Rendus. PhysiqueWe consider the turbulent heat transport induced by thermal convection. The widespread belief is that the transport properties of the turbulent flow should be independent of the tiny molecular diffusivities for asymptotically strong driving, but the ...

Oscilatory Instability of Rayleigh-Marangoni-Benard Convection in Two-Layer System
, 2004 The convective instabilities in two or more superposed layers heated from below were studied extensively by many scientists due to several interfacial phenomena in nature and crystal growth application.

Traveling-wave wall states in rotating Rayleigh-Bénard convection [PDF]
, 1993 We show that the wall-localized convection states observed in Rayleigh-Bénard convection in rotating cylindrical cells can be explained in terms of a geometry-independent traveling-wave wall state.

Internally heated convection and Rayleigh-Bénard convection
, 2007 This Brief describes six basic models of buoyancy-driven convection in a fluid layer: three configurations of internally heated convection and three configurations of Rayleigh-Bénard convection.

Bursting dynamics in Rayleigh-Bénard convection
, 2017 We report bursting dynamics in a parametrically driven Rayleigh-Bénard convection (RBC) model of low Prandtl-number fluids with free-slip boundary conditions. A four dimensional RBC model [P. Pal, K. Kumar, P. Maity, S.K. Dana, Phys. Rev.

Parallel adaptive finite element methods for problems in natural convection
, 2008 textNumerical simulations of combined buoyant and surface tension driven flow, also known as Rayleigh-Bénard-Marangoni (RBM) convection are conducted for heated fluid layers of small aspect ratio (defined as the ratio of the horizontal extent of the ...
