Abstract
Pure liquid-liquid diffusion driven by concentration gradients is hard to study in normal gravity environments because of the contributing of convection and sedimentation to the mass transfer process. The paper presents the influence of gravity to mass transfer in diffusion process using an experimental technique based on optical digital interferometry for measuring mass transfer coefficients. The diffusion experiments are monitored by a March-Zehnder interferometer which can record all mass distribution information. Such information is not only available at the steady state, but within the whole diffusion process. The time-dependent evolution of the concentration field allows the measurement of diffusion coefficient. The measurements of transport coefficients have been performed in water/glucose mixture. The experiment apparatus are also set up for TF-1 rocket which can get the results in microgravity environment. So the significant influence of gravity can be demonstrated obviously.
