This year’s event ACADEMY OF MECHANICAL ENGINEERING 2023 (Akademija strojništva) took place in Slovenia’s main cultural and congress centre, Cankarjev dom, where the most innovative personalities from industry and academic sphere were awarded.

At the event researchers from the academic and industrial environment presented their innovative engineering contributions and this included an article titled“A data-driven reduced-order model for evaluating energy flows in a topologically complex district heating system” which was supported by the 3DiVERSE project.

In the paper, authors Marko Keber, Andrej Kitanovski, Katja Klinar, and Tine Seljak from the Faculty of Mechanical Engineering at University of Ljubljana presented a reduced-order model, which simplifies the complex topology of a district heating system to a set of nodes, enables computationally efficient analysis of different system setups defined by operational data. Since conductive properties of insulating material have a dominant effect on system behaviour, a single control parameter, the equivalent thickness of deficient insulation, can be used to tune the model so that satisfactory precision can be obtained even with minimal data about the configuration of consumers.
