Evolution of the coupled Bénard-Marangoni convection

Physical Review A, 1989
A weakly nonlinear theory that describes the onset of the combined Benard-Marangoni convection is presented. All relevant transport coefficients are taken to be temperature dependent. When the boundaries are, thermally, nearly insulating, the instability is weak and the perturbed fluid-air interface is found to be proportional to the temperature field ...

Thermovision applied to Benard-Marangoni convection

Applied Optics, 1982
Thermovision is a technique which visualizes the superficial temperatures of materials through the infrared radiation emitted by their surface. This technique is applied to a study of Benard-Marangoni convection. Isotherms of convective cells (hexagons as well as pentagonal and heptagonal defects) are presented.

Control of long-wavelength Marangoni–Bénard convection

Journal of Fluid Mechanics, 1999
A nonlinear feedback control strategy for delaying the onset and eliminating the subcritical nature of long-wavelength Marangoni–Bénard convection is investigated based on an evolution equation. A control temperature is applied to the lower wall in a gas–liquid layer otherwise heated uniformly from below.

A marangoni-convection-driven chaotic flow

Nonlinear Analysis: Theory, Methods & Applications, 1997
The author continues previous work of Aref, Ottino and others which linked the mixing of viscous fluids to chaos theory.

On doubly diffusive Marangoni convection

Chemical Engineering Science, 1995
The paper deals with the cellular convection resulting from the parallel mass transfer of two components. It is shown that the case analysed cannot be regarded as fully equivalent to that of the simultaneous mass and heat transport due to the effect of the phenomena occurring in the Gibbs dividing layer.

Marangoni convection in a tear film

Journal of Colloid and Interface Science, 1982
Abstract It is shown theoretically that Marangoni convection may exist in a human tear film due to the diffusion of mucin. However, the temperature drop across the tear film is not capable of generating Marangoni convection.

Square Patterns in Bénard-Marangoni Convection

Physical Review Letters, 1996
The evidence of square patterns in B\'enard-Marangoni convection relatively far above threshold is demonstrated for the first time by means of a direct numerical integration of the three-dimensional Navier-Stokes equations. It is shown that regular squares are only obtained for a finite Prandtl number.

Marangoni Convection With a Deforming Interface

Heat Transfer in Microgravity Systems, 1994
Abstract A computational study of thermocapillary, small Pr convection in a cavity with a deforming interface is performed. The free surface deflection is incorporated via domain perturbation in the limit of the Capillary number Ca → 0.
