So far; when modelling processes that demand for multi-phase and multi-component fluid property data; the user has to implement the required media models in the Modelica language as these types of fluids are not supported by Modelica.Media. This paper presents a first approach on how to implement fluid property data in process models from external sources and highlights which problems have to be overcome. Furthermore; it provides recommendations for the design of an efficient and user-friendly interface to external media packages.
