2.7 Physical phenomena and approaches to analysis and design
2.7.1 General
The analysis and design of energy geostructures rely on an appropriate understanding,
modelling and prediction of the phenomena that govern the behaviour and perfor-
mance of the considered technology. Three key physical phenomena characterise
energy geostructures: (1) heat transfer, (2) mass transfer and (3) deformation. Heat
