- Abstract
Under weightlessness, the effect of harmonic vibrations can easily induce average motions in fluids with density inhomogeneities. We will consider more particularly fluids near their critical point, where modifying temperature allows the important parameters of the problem (e.g. interfacial tension, density difference) to be varied in universal, scaling laws. We will thus study, below the critical point, the ordering of the gas-liquid interface (at equilibrium and during a phase transition) and, above the critical point, some thermovibrational instabilities. These studies have been performed in the Russian MIR station and in the MiniTexus and Maxus rockets of ESA and under magnetic compensation of gravity on earth.
