High-frequency driven capillary flows speed up the gas-liquid phase transition in zero-gravity conditions

Abstract : Under weightlessness conditions, the phase transition of fluids is driven only by slow capillary flows.We investigate the effect of high-frequency vibrations to reproduce some features of gravity effects andshow that such vibrations can greatly modify the phase transition kinetics. The investigation is performedinH2near its critical point (critical temperature 33 K) where critical slowing down enables the phasetransition process to be carefully studied. Gravity effects are compensated in a strong magnetic fieldgradient.
