Thermovibrational Instability Of Rayleigh-Marangoni-Benard Convection In Two-Layer Fluid Systems

, 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.

Sparse nonlinear models of chaotic electroconvection

Royal Society Open Science, 2021
Convection is a fundamental fluid transport phenomenon, where the large-scale motion of a fluid is driven, for example, by a thermal gradient or an electric potential. Modelling convection has given rise to the development of chaos theory and the reduced-

Study on the Instability of Two-Phase Flow in the Heat-Absorbing Tube of Trough Solar Collector

International Journal of Photoenergy, 2017
The Marangoni effect and Rayleigh-Benard effect in the two-phase region of solar trough heat-absorbing tube are simulated by FTM (front tracking method). Considering the Marangoni effect alone, although surface tension gradient and surface tension affect

Topographically Controlled Marangoni-Rayleigh-Bénard Convection in Liquid Metals

Fluids, 2021
Convection induced in a layer of liquid with a top free surface by a distribution of heating elements at the bottom can be seen as a variant of standard Marangoni–Rayleigh–Bénard Convection where in place of a flat boundary at constant temperature ...

Convection in fluid and porous media [PDF]

, 2003
The subject of convection in fluid and porous media is investigated. Particular attention is paid to penetrative convection. The first two chapters are devoted to penetrative convection when fluid overlies and saturates a porous medium.

ROTATING RAYLEIGH-BENARD CONVECTION

TASK Quarterly, 2008
In the this paper our results on the natural convection in an enclosed rotating cavity are presented. We have focused our attention on the influence of the Rayleigh and Taylor numbers on the flow structure.
