Introductory analysis of the Bénard-Marangoni convection
We describe experiments on Bénard-Marangoni convection which permit an useful understanding on the main concepts involved in this phenomenon as, for example, Bénard cells, aspect ratio, Rayleigh and Marangoni numbers, crispation number and critical conditions. In spite of the complexity of the convection theory, this work carries out a simple and introductory analysis of it which has the additi...

متن کاملTransient Rayleigh-Bénard-Marangoni solutal convection
Solutal driven flow is studied for a binary solution submitted to solvent evaporation at the upper free surface. Evaporation induces an increase in the solute concentration close to the free surface and solutal gradients may induce a convective flow driven by buoyancy and/or surface tension. This problem is studied numerically, using several assumptions deduced from previous experiments on poly...
متن کاملNumerical investigation of bubble-induced Marangoni convection.
The liquid motion induced by surface tension variation, termed the thermocapillary or Marangoni effect, and its contribution to boiling heat transfer has long been a very controversial issue. In the past this convection was not the subject of much attention because, under terrestrial conditions, it is superimposed by the strong buoyancy convection, which makes it difficult to obtain quantitativ...
