A Multi-Relaxation-Time Lattice Boltzmann Method on Non- Uniform Grids for Large Eddy Simulation of Rayleigh-Bénard Convection Using Two Sub-Grid Scale Models

Journal of Applied Fluid Mechanics, 2014
In the present work, for the first time, the application of a Multi-Relaxation-Time Lattice Boltzmann (MRT-LB) model for large-eddy simulation (LES) of turbulent thermally driven flows on non-uniform grids is considered.

Evolution of the Rayleigh-Benard Convection in a Rectangular Box

Journal of the Physical Society of Japan, 1996
We report the results on the MAC numerical simulations of the Rayleigh-Benard convection for a Boussinesq fluid with the Prandtl number P r =6 confined in a rectangular box with the aspect ratios Γ x =3.0 and Γ y =1.5. With increase of the Rayleigh number, the initial state with two parallel steady rolls undergoes a successive series of transitions in ...

Time-periodic Heating of Rayleigh-Benard Convection

Physica Scripta, 2002
Summary: The linear stability problem for a fluid in a classical Benard configuration is examined. In addition to a steady temperature difference between the walls of the fluid layer, a time-dependent perturbation is applied to the wall temperatures. The time-dependent perturbation is expressed in Fourier series.

Rayleigh-Benard Convection in an Electrochemical Redox Cell

Science, 1984
Damped voltage oscillations occur when current steps are applied to a cell consisting of a thin layer of Fe 111 /Fe 11 electrolyte sandwiched between horizontal, parallel, platinized platinum electrodes.

Rayleigh–Benard convection in rotating fluids

International Journal of Heat and Mass Transfer, 2008
Abstract Linear and weakly nonlinear properties of Rayleigh–Benard convection in rotating fluids are investigated. Linear stability analysis is studied to investigate analytically the effect of Coriolis force on gravity-driven convection for idealised stress-free boundary conditions.

Two-dimensional Rayleigh-Benard convection

Journal of Fluid Mechanics, 1973
Two-dimensional convection in a Boussinesq fluid confined between free boundaries is studied in a series of numerical experiments. Earlier calculations by Fromm and Veronis were limited to a maximum Rayleigh number R 50 times the critical value R, for linear instability. This range is extended to 1000R c .
