In situ measurements of thermally loaded rock and evaluation of an experiment with a 3D numerical model

- The rock heating experiment demonstrates the operation of cyclic heat energy storage.
- Temperatures and stresses are monitored and fitted by a numerical model.
- A uniform elastic modulus is calibrated jointly for model and sensor value conversion.
- Stresses and deformation are well explained by the linear elastic model in most cases.
- Energy balance and storage efficiency are calculated by the numerical model.
