Erratum: Implementation of a perturbation model for a dilute binary liquid and comparison of model mass diffusion coefficients with microgravity experiment results for liquid Pb 1 wt% Au

Abstract

The estimation of mass diffusion coefficients, through Earth-bound experiments, remains difficult, due to the frequent occurrence of dominating convective flows resulting from gravity-driven density gradients caused by temperature and concentration gradients. To partly remedy this, a series of capillary mass diffusion experiments has been performed in microgravity on a number of different space platforms, sometimes performed on a microgravity isolation mount, to further reduce the platform operational noise referred to as “g-jitter”. Theoretical comparisons are sought for the experimental observations. Two numerical models have been developed based on perturbation theory. We have used the Lado criteria for minimizing the difference in free energy between the multispecies liquid of interest and a reference hard-sphere liquid. The hard-sphere liquid is characterized by the rational function approximation of the partial radial distribution functions. The effective embedded atom like glue potential has been u...
