The paper deals with the new types of dissipative layers, called Marangoni boundary layers, that can be formed in surface driven flows. Plane similar solutions are studied for the case in which the flow fields of the two interfacing fluids are couple

The paper derives, on a coherent postulatory basis, the basic set of equations needed to completely describe the thermodynamics and dynamics of pure interfaces. This set comprises: the equilibrium constitutive equation giving the surface tension as a

Plane Poiseuille flow of two immiscible fluids in a non-isothermal “capillary” channel under the combined action of pressure gradients, gravitational fields and surface tension gradients is studied. Conditions for attaining a Poiseuille-type regi

The combined effects of buoyancy and Marangoni thermal stresses for Stokes regimes in a plane Plateau type configuration are studied. The appropriate mathematical formulation for Stokes regimes of arbitrary immiscible interfacing liquids in the prese

The effects of temperature dependence of the diffusion coefficients on the solution fields of Thermal Marangoni Flows in micro-gravity is analyzed by using an unsteady—variable mesh—two dimensional—finite difference numerical code to solve the

A system of two interfacing immiscible fluids subject to an imposed temperature difference in a gravity field is considered. The fluids, the gravity level, the temperature difference and the extension of the interface are arbitrary. An order of magni
