Parallel adaptive finite element methods for problems in natural convection [PDF]

, 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 ...

Study of regular and chaotic dynamics in double diffusive Rayleigh-Bénard convection of a micropolar fluid

Results in Engineering
The study explores the behaviour of a micropolar fluid subjected to a double-diffusive Rayleigh-Bénard configuration, focusing on the emergence of regular convection, periodic motion, and chaotic dynamics across a broad range of the scaled Rayleigh ...

Rayleigh-Bénard convection of Casson fluids [PDF]

, 2018
International audienceThis study aims at investigating numerically the Rayleigh-Bénard Convection (RBC) in viscoplastic fluids. A Casson fluid is considered in a bidimensional square cavity heated from below. The effects of the dimensionless yield stress,

Resolving the fine-scale structure in turbulent Rayleigh–Bénard convection

New Journal of Physics, 2013
We present high-resolution direct numerical simulation studies of turbulent Rayleigh–Bénard convection in a closed cylindrical cell with an aspect ratio of one. The focus of our analysis is on the finest scales of convective turbulence, in particular the

Rayleigh-Benard convection in a viscoelastic fluid-filled high-porosity medium with nonuniform basic temperature gradient

International Journal of Mathematics and Mathematical Sciences, 2001
The qualitative effect of nonuniform temperature gradient on the linear stability analysis of the Rayleigh-Benard convection problem in a Boussinesquian, viscoelastic fluid-filled, high-porosity medium is studied numerically using the single-term ...

Reduced basis method applied to a convective stability problem

Journal of Mathematics in Industry, 2018
Numerical reduced basis methods are instrumental to solve parameter dependent partial differential equations problems in case of many queries. Bifurcation and instability problems have these characteristics as different solutions emerge by varying a ...

Radiatively driven convection: diffusivity-free regimes of geophysical and astrophysical flows in the laboratory

Comptes Rendus. Physique
We 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 ...
