Modulation of Marangoni convection in liquid films

Advances in Colloid and Interface Science, 2015
Non-isothermal liquid films are subject to short- and long-wave modes of Marangoni instability. The short-wave instability leads to the development of convection cells, whereas long-wave instability is one of the primary causes of the film rupture. In this paper different methods for modulation of Marangoni convection and Marangoni-induced interface ...

Nonlinear model for Marangoni convection

Physical Review E, 2000
We have constructed a Lorenz-like model for Marangoni convection with finite wave number in large aspect ratio situations. Within the model, there is exchange of stabilities at the onset of convection and beyond the onset there is onset of oscillations due to the presence of surface fluctuations.

Inertial Bénard–Marangoni convection

Journal of Fluid Mechanics, 1997
Two-dimensional surface-tension-driven Bénard convection in a layer with a free-slip bottom is investigated in the limit of small Prandtl number using accurate numerical simulations with a pseudospectral method complemented by linear stability analysis and a perturbation method. It is found that the system attains a steady state consisting

Marangoni convection on an inhomogeneous substrate

Physical Review E, 1999
We consider an inhomogeneous substrate for Marangoni convection. The inhomogeneity shows up in a nonuniform temperature distribution which we model by a periodic variation. The response can exhibit parametric resonance. Both resonant and nonresonant responses are considered and a possible strong effect on wave number selection indicated.

Marangoni Convection With a Deformable Surface

Journal of Applied Mechanics, 1994
Double diffusive convection is considered in a semi-infinite domain, bounded below by a solid surface and above by a gas interface. Temperature and concentration gradients are imposed normal to the free surface and the linear stability of the fluid is examined. Traditional analyses are extended to include the effects of a deformable free surface.

Chemo-Marangoni Convection

Journal of Colloid and Interface Science, 1993
A linear convective stability analysis has been carried out for a liquid-liquid system subject to an interfacial chemical reaction whose reactants are capable of changing the surface tension. Conditions for the occurrence of chemocapillary Marangoni convection have been defined and their dependence on a number of physicochemical parameters, including ...

Marangoni Convection in a Square Porous Cavity

International Journal of Computational Fluid Dynamics, 1998
Convection may occur in different processes, which may not depend on the buoyancy force. One of these processes is due to the surface tension gradient also known as Marangoni convection. Such convection creates a strong flow leading to instability for a fluid. Porous medium consists of solid matrix with an interconnected void filled with a fluid. A new
