In many cases, the efficiency of the melting process acts as the primary throughput-limiting factor. If the material melts too late in the process, it may not be sufficiently mixed, resulting in substandard product quality. Accurate prediction of the melting process is therefore essential for efficient and cost-effective machine design. A practical method for engineers is the modeling of the melting process using mathematical–physical models that can be solved without complex numerical methods. These models enable rapid calculations while still providing sufficient predictive accuracy. This study revisits the modified Tadmor model by Potente, which describes the melting process and predicts the delay-zone length, extending from the hopper front edge to the point of melt pool formation. Based on extensive experimental investigations, this model is adapted by redefining the flow temperatures at the phase boundary and accounting for surface porosity at the beginning of the melting zone. Additionally, the effect of variable solid bed dynamics on model accuracy is examined. Significant model improvements were achieved by accounting for reduced heat flow into the solid bed due to the porous surface structure in the solid conveying zone, along with a new assumption for the flow temperature at the phase boundary between the solid bed and melt film.}}, author = {{Schöppner, Volker and Brüning, Florian and Knaup, Felix}}, journal = {{Polymers}}, keywords = {{delay zone, extrusion, melting modeling}}, number = {{22}}, pages = {{3130}}, title = {{{Improvement in an Analytical Approach for Modeling the Melting Process in Single-Screw Extruders}}}, doi = {{10.3390/polym16223130}}, volume = {{16}}, year = {{2024}}, } @inbook{56177, author = {{Knoll, Lisa}}, booktitle = {{The Routledge International Handbook of Valuation and Society}}, editor = {{Krüger, Anne and Peetz, Thorsten and Schaefer, Hilmar}}, pages = {{316--325}}, publisher = {{Routledge}}, title = {{{Valuation and Sustainability}}}, year = {{2024}}, } @book{58692, editor = {{Alpsancar, Suzana}}, isbn = {{ISBN 978-3-7560-1830-7}}, publisher = {{Nomos}}, title = {{{ Der Sog des Neuen und der Schock des Alten Jahrbuch Technikphilosophie 2024 }}}, volume = {{10.
