WebANNALES DE L INSTITUT HENRI POINCARE-ANALYSE NON LINEAIRE, 37 (6), 1299-1343. Resumen: This paper studies the dynamics of an incompressible fluid driven by gravity and capillarity forces in a porous medium. The main interest is the stabilization of the fluid in Rayleigh-Taylor unstable situations where the ... Webinduced surface instabilities. We then compare potential energies of different instability patterns, and construct aquantitative phase dia-gram that accounts for all instability patterns discussed above, by assuming the current pattern seeks the lowest potential energy among all possible configurations.
