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}}, } @inproceedings{59256, author = {{Arsenyeva, Olga and Kapustenko, Petro and Varbanov, Petar Sabev and Tovaznyanskyy, Leonid}}, booktitle = {{Proceedings of the 27th Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction, 25 – 28 August 2024, Xi’an, China}}, location = {{ Xi’an, China}}, title = {{{Heat Transfer Enhancement in Compact Heat Exchangers with Channels of Different Geometries and Size}}}, year = {{2024}}, } @article{59269, abstract = {{Ferroelectric materials play a crucial role in a broad range of technologies due to their unique properties that are deeply connected to the pattern and behavior of their ferroelectric (FE) domains. Chief among them, barium titanate (BaTiO3; BTO) sees widespread applications such as in electronics but equally is a ferroelectric model system for fundamental research, e.g., to study the interplay of such FE domains, the domain walls (DWs), and their macroscopic properties, owed to BTO’s multiple and experimentally accessible phase transitions. Here, we employ Second Harmonic Generation Microscopy (SHGM) to in situ investigate the cubic-to-tetragonal (at ∼126°C) and the tetragonal-to-orthorhombic (at ∼5°C) phase transition in single-crystalline BTO via three-dimensional (3D) DW mapping. We demonstrate that SHGM imaging provides the direct visualization of FE domain switching as well as the domain dynamics in 3D, shedding light on the interplay of the domain structure and phase transition. These results allow us to extract the different transition temperatures locally, to unveil the hysteresis behavior, and to determine the type of phase transition at play (first/second order) from the recorded SHGM data. The capabilities of SHGM in uncovering these crucial phenomena can easily be applied to other ferroelectrics to provide new possibilities for in situ engineering of advanced ferroic devices.}}, author = {{Kirbus, Benjamin and Seddon, Samuel D. and Kiseleva, Iuliia and Beyreuther, Elke and Rüsing, Michael and Eng, Lukas M.}}, issn = {{0021-8979}}, journal = {{Journal of Applied Physics}}, number = {{15}}, publisher = {{AIP Publishing}}, title = {{{Probing ferroelectric phase transitions in barium titanate single crystals via in-situ second harmonic generation microscopy}}}, doi = {{10.1063/5.0237769}}, volume = {{136}}, year = {{2024}}, }
