Marangoni Effect in Material Engineering. Marangoni Effects in Surfactant Solution.

MPP Solution of Rayleigh - Bénard - Marangoni Flows

A domain decomposition strategy and parallel gradient-type iterative solution scheme have been developed and implemented for computation of complex 3D viscous flow problems involving heat transfer and surface tension effects. Special attention has been paid to the kernels for the computationally intensive matrix-vector products and dot products, to memory management, and to overlapping communic...

Title of dissertation: THE EFFECT OF SURFACTANT VAPOR ON MARANGONI CONVECTION IN ABSORPTION AND CONDENSATION Zhe Yuan, Doctor of Philosophy, 2005 Dissertation directed by: Dr. Keith E. Herold, Associate Professor, Department of Mechanical Engineering Mass and heat transfer enhancement by the addition of a class of surfactant additives is in common use in absorption machines based on aqueous lit...

Thermally driven Marangoni surfers

Precision Marangoni-driven patterning.

A Marangoni flow is shown to occur when a polymer film possessing a spatially-defined surface energy pattern is heated above its glass transition to the liquid state. This can be harnessed to rapidly manufacture polymer films possessing prescribed height profiles. To quantify and verify this phenomenon, a model is described here which accurately predicts the formation, growth, and eventual diss...
