Evolution of the Rayleigh-Benard Convection in a Rectangular Box
Journal of the Physical Society of Japan, 1996We 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 ...

Thermovibrational instability of Rayleigh–Marangoni–Benard convection in two-layer fluid systems
Advances in Space Research, 2008 The thermovibrational instability of Rayleigh-Marangoni-Benard convection in a two-layer system under the high-frequency vibration has been investigated by linear instability analysis in the present paper.

Time-periodic Heating of Rayleigh-Benard Convection
Physica Scripta, 2002Summary: 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.

Effects of Prandtl number in quasi-two-dimensional Rayleigh–Bénard convection
Journal of Fluid Mechanics, 2021We report an experimental study of the Prandtl-number effects in quasi-two-dimensional (quasi-2-D) Rayleigh–Bénard convection. The experiments were conducted in four rectangular convection cells over the Prandtl-number range of $11.7 \leqslant Pr ...

Rayleigh-Benard Convection in an Electrochemical Redox Cell
Science, 1984Damped 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.

The persistence of large-scale circulation in Rayleigh–Bénard convection
Journal of Fluid Mechanics, 2021The time-averaged strength $\langle \delta \rangle /\varDelta$ of a convective cellular pattern and large-scale circulation (LSC) in the turbulence regime of turbulent Rayleigh–Bénard convection exhibits a sequence of sharp changes with the Rayleigh ...

Rayleigh–Benard convection in rotating fluids
International Journal of Heat and Mass Transfer, 2008Abstract 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, 1973Two-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 .

In this paper, the onset of Rayleigh–Benard convection of cold water near its density maximum in a vertical cylindrical container and the stability of the steady axisymmetric flow were studied by using linear stability analysis. The results show that the
