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."}],"publication":"Polymers","type":"journal_article","doi":"10.3390/polym16223130","title":"Improvement in an Analytical Approach for Modeling the Melting Process in Single-Screw Extruders","volume":16,"author":[{"first_name":"Volker","last_name":"Schöppner","id":"20530","full_name":"Schöppner, Volker"},{"id":"72920","full_name":"Brüning, Florian","last_name":"Brüning","first_name":"Florian"},{"last_name":"Knaup","full_name":"Knaup, Felix","id":"45124","first_name":"Felix"}],"date_created":"2025-04-02T09:51:32Z","date_updated":"2025-04-02T11:21:00Z","intvolume":"        16","page":"3130","citation":{"mla":"Schöppner, Volker, et al. “Improvement in an Analytical Approach for Modeling the Melting Process in Single-Screw Extruders.” <i>Polymers</i>, vol. 16, no. 22, 2024, p. 3130, doi:<a href=\"https://doi.org/10.3390/polym16223130\">10.3390/polym16223130</a>.","short":"V.

Based on a modified distributed system topology utilizing a time division multiple access (TDMA) protocol, i.e., Flex Ray, we present a self-organized distributed coordinator concept which performs the self-reconfiguration in the case of node failures. We introduce a distributed coordinator, which utilizes redundant slots in the Flex Ray communication schedule and combines messages in configured protocol frames and slots to avoid a complete bus restart. As such, the self-reconfiguration is realized by means of predetermined information about resulting changes in the communication dependencies and (re-)assignments determined in the design phase. To retrieve the necessary information, we present an analytical approach, which determines a combined solution for the initial configuration and all possible reconfigurations for the remaining nodes of the Flex Ray network in case of node failures. Hence, through this method we can design self-reconfiguring network-based systems enabling the handling of node failures for an increased fault tolerance.","lang":"eng"}],"type":"conference","language":[{"iso":"eng"}],"keyword":["Real time systems","Fault tolerant systems","Schedules","Protocols","Redundancy","Delay"],"user_id":"5786","department":[{"_id":"672"}],"_id":"36922"},{"keyword":["Timing","Programming","Automotive engineering","Application software","Hardware","Computer architecture","Communication system software","Software architecture","Delay","Software standards"],"language":[{"iso":"eng"}],"_id":"37011","user_id":"5786","department":[{"_id":"672"}],"abstract":[{"lang":"eng","text":"Safety-critical automotive systems must fulfill hard real-time constraints for reliability and safety.

The receivers treat the reflected paths also reaching the receiver antenna as disturbance which has to be suppressed. Multipath affects the tracking accuracy by resulting in a degeneration of the S-curve of the DLL (delay locked loop). Nowadays the future European systems GALILEO and GPSIIF/III with two new signals are on the way to the market and it is time to think about new receiver structures. Therefore we investigated if it is possible to use multipath for navigation constructively.","lang":"eng"}],"status":"public"}]
