Marangoni convection in a binary liquid layer with Soret effect at small Lewis number: Linear stability analysis

Physics of Fluids, 2009
We consider surface-tension-driven convection in a layer of a binary mixture. A linear stability problem is studied in the presence of both thermocapillary and solutocapillary effects. Assuming the Lewis and Biot numbers to be small, we develop the long wave theory and find both monotonic and oscillatory modes.

Linear and nonlinear theory of long-wave Marangoni instability with the Soret effect at finite Biot numbers

Physics of Fluids, 2006
We investigate the long-wave Marangoni instability in binary-liquid layers in the presence of the Soret effect in the case of finite Biot numbers. Linear stability theory reveals both long-wave monotonic and oscillatory modes of instability in various parameter domains.

Analytical investigation on the combined impacts of the Soret and Dufour phenomenon in the forced convective flow of a non-Newtonian nanofluid by the movable Riga device

Waves in Random and Complex Media, 2023
This paper examined the MHD flow over the Riga surface in the presence of a permeable medium with Soret and Dufour effects. The Cattaneo-Christov model is adopted to scrutinize thermal and mass diffusion.

Soret and Dufour effects on dissipative Jeffrey nanofluid flow over a curved surface with nonlinear slip, activation energy and entropy generation

Waves in Random and Complex Media, 2023
Nanofluids have potential abilities and thermal features and provide more efficient results of heat transfer when compared with common liquid. Therefore, the major novel aspect of the current analysis is to analyze the entropy production and thermal ...

Effects of Soret and Dufour Numbers on the Three-Dimensional MHD Flow of Micropolar Fluid Containing Gyrotactic Microorganisms Over a Bidirectional Stretching Sheet With Cattaneo–Christov Heat and Mass Flux Model

Journal of Heat Transfer, 2022
Abstract Stretching flow problems have several real-world applications in engineering, biological, and industrial fields. The real-world applications of the stretching sheet flow problems are continuous cooling of fiber, manufacturing of rubber and plastics sheets, metal-working processes, crystal growth processes, drawing of the ...

Long-Wave Marangoni Instability in a Binary-Liquid Layer with a Deformable Interface in the Presence of the Soret Effect: The Case of Finite Biot Numbers

Journal of Non-Equilibrium Thermodynamics, 2007
An incompressible binary liquid with a deformable free surface is adjacent to a solid layer, heated or cooled from below. The surface tension depends linearly on both the temperature and the solute concentration. The authors reveal the emergence of the long-wave Marangoni instabilities for finite Biot numbers in the limit of small Lewis and Galileo ...
