ABSTRACT

This contribution surveys the various scales at which multi-phase systems can be modelled (effective field modelling, capturing large scale discontinuities at the largest scale, down to molecular dynamics modelling at the smallest scale) and shows how a multiscale treatment is necessary to capture the important flow features. The multiscale approach is illustrated with several examples.
