The research group Multiphase Models
focuses on the detailed modeling of com-

for metallurgical and chemical processes.
High resolution numerical studies of dif-
ferent sections in complex technological
systems facilitate the discovery of new
correlations and are the basis for advan-
ced models in the fields of phase change
and conversion processes. The coopera-
