Modeling of consistent rheological and thermodynamic material data for process simulations
Any process simulation in polymer engineering is based on conservation equations, which refer to comprehensive knowledge about material properties. These empirically examined properties, such as viscosity, specific enthalpy (specific heat capacity), density, and thermal conductivity are represented in the simulation via mathematical material models. However, the way of gathering rheological and thermodynamic material data influences the accuracy of the material model and thus the simulation output. Hence, the importance of an accurate material model is obvious. With respect to this the influence of measuring methods on the material model and a procedure to model consistent material data at process-relevant heating/cooling rates is described.

The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
