A heat transfer correlation of Poiseuille-Rayleigh-Bénard convection in the thermal entrance region of a horizontal rectangular channel

Case Studies in Thermal Engineering
In order to understand heat transfer characteristics and obtain a heat transfer correlation of Poiseuille-Rayleigh-Bénard (P-R-B) convection in the thermal entrance region of a horizontal rectangular channel, we performed a series of the direct numerical

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 ...

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 ...

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 ...

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 ...

Effects of modulation on Rayleigh-Benard convection. Part I

International Journal of Mathematics and Mathematical Sciences, 2004
The linear stability of a horizontal layer of fluid heated from below and above is considered. In addition to a steady temperature difference between the walls of the fluid layer, a time-dependent periodic perturbation is applied to the wall temperatures.
