TLDR
In this paper, the dissipative layers, called Marangoni boundary layers, that can be formed along the interface of two immiscible fluids, in surface driven flows are studied under the hypothesis that the flow fields of the two interfacing fluids are uncoupled.Citations

Particle shape effects on Marangoni convection boundary layer flow of a nanofluid
TL;DR: In this paper, the particle shape effects on Marangoni convection boundary layer flow of a nanofluid were investigated. But the authors focused on the effect of shape and size of the particles on the surface temperature gradient.

Similarity solutions for MHD thermosolutal Marangoni convection over a flat surface in the presence of heat generation or absorption effects
Ali F. Al-Mudhaf,Ali J. Chamkha +1 more
TL;DR: In this article, the authors studied the effect of a first-order chemical reaction on the steady, laminar, thermosolutal Marangoni convection flow of an electrically-conducting fluid along a vertical permeable surface in the presence of a magnetic field, heat generation or absorption and a first order chemical reaction effects.

Exact analytical results for the thermosolutal MHD Marangoni boundary layers
Eugen Magyari,Ali J. Chamkha +1 more
TL;DR: In this article, the steady laminar magnetohydrodynamic (MHD) thermosolutal Marangoni convection in the presence of a uniform applied magnetic field is considered in the boundary layer approximation.
Surface and buoyancy driven free convection
TL;DR: In this paper, a system of two interfacing immiscible fluids subject to an imposed temperature difference in a gravity field is considered, and an order of magnitude analysis is applied to determine: (i) the types of flow regimes that can be attained in natural, Marangoni or combined free convection; (ii) how the problem's data identify which type of free convective and of flow regime prevails in each specific case.

TL;DR: In this article, the steady laminar thermosolutal Marangoni convection in the presence of temperature-dependent volumetric heat sources/sinks as well as of a first-order chemical reaction is considered.

On an equation occurring in Falkner and Skan's approximate treatment of the equations of the boundary layer
TL;DR: In this paper, it was shown that for the application to be made of the solution the appropriate condition is that y′ → 1 from below, and as rapidly as possible, as x → ∞.

Particle drag and heat transfer in rocket nozzles
TL;DR: In this article, an empirical expression for the drag coefficient of a spherical particle in flow regimes such as occur in solid propellant rocket exhausts is presented, and the effects of these relationships on computed particle velocities and temperatures are shown.

TL;DR: In this article, the Marangoni boundary layers, which can be formed in surface driven flows, are studied for the case in which the flow fields of the two interfacing fluids are coupled kinematically and thermally.
