E.L. Koschmieder,S.G. Pallas +1 more
TLDR
In this article, the authors measured the heat transfer through a shallow, horizontal, circular fluid layer, heated uniformly from below and cooled uniformly from above, and the lid of the silicone oil layer was a sapphire crystal which permitted visual observation of the flow during the heat-transfer measurements.About:

Pattern formation outside of equilibrium
Michael Cross,P. C. Hohenberg +1 more
TL;DR: A comprehensive review of spatiotemporal pattern formation in systems driven away from equilibrium is presented in this article, with emphasis on comparisons between theory and quantitative experiments, and a classification of patterns in terms of the characteristic wave vector q 0 and frequency ω 0 of the instability.

Recent Developments in Rayleigh-Bénard Convection
TL;DR: In this article, a review summarizes results for Rayleigh-Benard convection that have been obtained over the past decade or so, focusing on convection in compressed gases and gas mixtures with Prandtl numbers near one and smaller.
Journal ArticleDOI
Convective instability: A physicist's approach
TL;DR: In this paper, a number of apparently disparate problems from engineering, meteorology, geophysics, fluid mechanics and applied mathematics are considered under the unifying heading of natural convection.
Journal ArticleDOI
Rayleigh-bénard convection
TL;DR: In this paper, a physicist's approach to Rayleigh-Benard convection is presented with physical reasons for the existence of a critical threshold and a detailed examination of the spatial organization is made with discussion of ordered and disordered structures.
Journal ArticleDOI
Stability and fluctuations of a spatially periodic convective flow
Yves Pomeau,Paul Manneville +1 more
TL;DR: In this paper, the authors used a model equation to analyze the onset of convection for a roll instability and showed that the wavelength increase follows from a variational approach, where the phase diffusion turns out to be unstable against compression (or dilatation) and torsion of the rolls.

On convection cells induced by surface tension
TL;DR: In this paper, a mechanism was proposed by which cellular convective motion of the type observed by H. Benard, which hitherto has been attributed to the action of buoyancy forces, can also be induced by surface tension forces.
Journal ArticleDOI
The Heat Transport and Spectrum of Thermal Turbulence
TL;DR: In this article, an upper limit to the heat transport is found subject to the constraint that some minimum eddy size exists which is effective in this transport, and the spectrum of convecting motions, the mean thermal gradients at each point and the eddy conductivity are then determined in terms of the minimum edddy size.

On the stability of steady finite amplitude convection
TL;DR: In this paper, a systematic method is presented which yields the finite-amplitude steady solutions by means of successive approximations, and a similar procedure is applied to the stability problem for these steady finite amplitude solutions with the result that three-dimensional solutions are unstable but there is a class of two-dimensional flows which are stable.
Journal ArticleDOI
Surface tension and buoyancy effects in cellular convection
TL;DR: In this article, a Fourier series method has been used to obtain the eigenvalue equation for the case where the lower boundary surface is a rigid conductor and the upper free surface is subject to a general thermal condition.
Journal ArticleDOI
Surface Tension as the Cause of Bénard Cells and Surface Deformation in a Liquid Film
TL;DR: Benard as mentioned in this paper observed a cellular deformation produced on the free surface of a liquid film the bottom surface of which (in contact with a floor) was uniformly heated and hotter than its top surface.
