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

open access: yesResults 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 ...

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

open access: yesNew 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

Reduced basis method applied to a convective stability problem

open access: yesJournal 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

open access: yesComptes 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 ...

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

open access: yesInternational 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 ...

Initial-boundary layer associated with the 3-D Boussinesq system for Rayleigh-Benard convection

open access: yesElectronic Journal of Differential Equations, 2020
This article concerns the initial-boundary layer effects of the 3-D incompressible Boussinesq system for Rayleigh-Benard convection with ill-prepared initial data.
