Naissance de la convection dans une cavité poreuse 3D soumise à des vibrations de hautes fréquences

Abstract

Analytical techniques are used to study the onset of convection in three-dimensional boxes of fluid saturated porous material heated from below and subjected to vertical high-frequency vibration. Increasing the vibration amplitude delays the onset of convection and may even create subcritical solutions so as generate different structures of flows.
