Model-based experimental analysis of multicomponent diffusion in liquids

Predictive models for diffusion coefficients in liquids contain today still substantial uncertainty. This is due to the lack of sufficient measurement data. Established methods for the determination of diffusion coefficients require high experimental effort. Several experiments are e.g. required to perform measurements for multicomponent mixtures at a single composition. Therefore, a new measurement technique for diffusion coefficients in multicomponent mixtures is developed in this work. The new approach combines model-based methods for experimental design and data analysis with modern spectroscopic measurement techniques. In this talk an overview of the progress made to the analysis of binary and ternary mixtures is given.
