This data should be considered with its associated publication: Alice Di Donnaa, FleurLoveridge, Miriam Piemontese, Marco Barla. The role of ground conditions on the heat exchange potential of energy walls. Geomechanics for Energy and the Environment. https://doi.org/10.1016/j.gete.2020.100199 The following data is available: FIgure3.xls - presents the heat flux against time data for the reference case simulations Figure8.xls - presents the heat flux at 30 days for various geological conditions. This data was used to derive the design chart (for a constant temperature boundary) presented in the publication. Figure9.xls - presents the heat flux at 30 days for various geological conditions. This data was used to derive the design chart (for a heat transfer coefficient boundary) presented in the publication. Each data file contains associated input parameters, however Di Donna et al (2020) should be referred to for full details of all assumptions, boundary conditions, and input parameters.
