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

Thermal vibrational convection in near-critical fluids. Part 2. Weakly non-uniform heating [PDF]

, 2006
The governing equations and effective boundary conditions to describe thermal vibrational convection in a near-critical fluid are derived with the help of the multiple-scale method and averaging procedure. In contrast to Part 1, this paper focuses on 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 ...

The effect of controlled vibrations on Rayleigh-Benard convection

Journal of Physics: Conference Series, 2021
Abstract The paper presents the results of a numerical study of convective heat transfer in a long horizontal layer heated from below with and without the vibration effect of the lower wall. The simulation was carried out on the basis of solving the Navier-Stokes 2D equations for an incompressible fluid in the Boussinesq approximation ...

Vortex structure in rotating Rayleigh-Benard convection [PDF]

, 1997
The authors investigate the flow patterns in a cylindrical rotating Rayleigh-Benard convection cell with radius-to-height ratio {Gamma} = 0.5. The Rayleigh number R is 2 x 10{sup 8}, the dimensionless rotation rate {Omega} varies from 10{sup 4} to 5 x 10{

Unsteady Heating of Rayleigh-Benard Convection

Zeitschrift für Naturforschung A, 2004
The linear thermal instability of a horizontal fluid layer with time-periodic temperature distribution is studied with the help of the Floquet theory. The time-dependent part of the temperature has been expressed in Fourier series. Disturbances are assumed to be infinitesimal. Only even solutions are considered.

Thermal effects on Rayleigh-Marangoni-Benard instability in a system of superposed fluid and porous layers

, 2010
Thermal effects of the heat transfer at free surface (represented by Biot number) on the Rayleigh-Marangoni-Benard instability in a system of liquid-porous layers with top free surface are investigated numerically.
