Coupling Subsurface and Above-Surface Models for Optimizing the Design of Borefields and District Heating and Cooling Systems

Jan 31, 2022
1.45 GB
Publicly accessible
Accurate dynamic energy simulation is important for the design and sizing of district heating and cooling systems with geothermal heat exchange for seasonal energy storage. Current modeling approaches in building and district energy simulation tools typically consider heat conduct...

Chemical Fracture Detection During Triaxial Deformation Tests

Aug 19, 2025
613.72 MB
Publicly accessible
A set of triaxial tests with sandstone, limestone, and granite samples was conducted to measure fluid chemistry before, during, and after rock fracture. The dataset here includes: 1) five triaxial test data files (xlxs), 2) one file containing the measured test tube volumes for th...
