Datenpaket: Experimental Data from a Packed-Bed Thermal Energy Storage System Using Liquid Metal as Heat Transfer Fluid during Charging and Discharging

Dieser Beitrag enthält die experimentellen Daten eines Festbett-Wärmespeichers mit Blei-Bismut-Eutektikum als Modellwärmeträgerfluid. Der Datensatz des sogenannten VESPA-Experiments umfasst Lade- und Entladeexperimente in einem Péclet-Zahlen-Bereich von $0,06$ bis $0,32$ und Temperaturdifferenzen im Speicher von $70~\mathrm{K}$ und $200~\mathrm{K}$.

In this contribution, the experimental data of a packed‑bed thermal energy storage system using a lead‑bismuth eutectic as model heat‑transfer fluid at laboratory scale are provided. The data set from the so‑called VESPA experiment includes charging and discharging experiments covering a Péclet number range from $0.06$ to $0.32$ and temperature differences in the storage of $70~\mathrm{K}$ and $200~\mathrm{K}$.

Raw data from a packed-bed thermal energy storage system during charging and discharging, using liquid metals as heat transfer fluid, is provided in CSV format. Technical drawings of the experimental setup are provided in PDF format.
