In this article, we experimentally investigate the non-linear behavior of a viscoplastic film flow down an inclined plane. We focus on the non-linear instabilities that appear as roll waves. Roll waves are generated by perturbing a permanent flow of

Efficient numerical models are derived for problems of natural convection and material solidification in a horizontal differentially heated slender cavity. These 2D1/2 models are obtained by averaging the equations of momentum, heat, and mass conserv

International audience; We combine an effective diffusivity model with a numerical approach initially proposed by Meyer (1981) to simulate transient heat and mass transfer phenomena in a directionally solidifying Sn-Bi rod. This particularly efficien
