“…We observed how the ToC contributed to the NDP and collected data through interviews, workshops, documents, and observation. The ToC applied in the project originated in the models for the Active Magnetic Regenerators (AMR) (Vieira et al, 2021), Magnetic Circuits (MC) (Trevizoli et al, 2015), Heat Exchangers (HEx) (Peixer et al, 2022), and Hydraulic System (HS) and were validated with data incoming from experimental means. The development team performed weekly integration events to build agreements on the DS.…”

The literature acknowledges the advantages of Set-Based Concurrent Engineering (SBCE), but there is a lack of models for its adoption and documented cases of its implementation, mostly on products with consolidated technology, which raises the possibility of expanding SBCE for highly innovative products. These projects often have extensive resource limitations, leading to computational tools and mathematical modelling as fundamental sources of information. This paper proposes a method for model-based Trade-off Curves (ToC) generation to support SBCE. We adopted it to develop a magnetic air conditioner. The use of model-based ToC enabled the narrowing of the design space and monitoring of the design parameters and performance metrics and enabled SBCE adoption in the design process. The main contributions of this research are presenting the state-of-the-art in ToC generation and application, proposing the model, and demonstrating SBCE in highly innovative projects, while its importance lies in the opportunity to further disseminate SBCE to different development environments.

“…Nearly spherical particles of La(Fe,Mn,Si) 13 Hy were produced by Vacuumschmelze GmbH & Co. KG, Hanau, Germany, as described in Ref. 7. The feed-stock material was extruded, cut into pieces, and mechanically spheronised to near sphere shaped particles.…”

“…The material family La(Fe,Si) 13 has become one of the most popular families to use in devices and prototypes. 2,4,[6][7][8] The asprepared transition temperatures of this material family are around 200 K. 9,10 When interstitial hydrogen is added, the transition temperature can be tailored in a broad range around room temperature, but actual control can be challenging due to the requirement of accurate hydrogenation. 11 When fully hydrogenated, substituting some Fe with Mn allows fine tuning of the transition temperature.…”

Virgin effect in spheres of LaFeSi-based alloys

A virgin phase transition is observed in spherical particles of the industrially relevant magnetocaloric material La(Fe,Mn,Si)13H y. Upon initial cooling, the phase transition is observed 2–3 K below the heating transition on all subsequent cooling and heating transitions. This virgin transition has been studied using differential scanning calorimetry and vibrating sample magnetometry. Incremental measurements show not only how the phase transition can be carefully approached but also that the initial full transformation requires cooling of about 6 K below the observed phase transformation. No signs of structural damage due to the thermal cycling were observed, neither macroscopically or by scanning electron microscopy.
