Abstract

Highlights
•3D numerical analyses are used to derive the semi-empirical pile g-functions.
•Fluid temperatures obtained in multiple pile patterns are analysed.
•Semi-empirical g-functions give fluid temperatures close to the 3D modelled.
•Semi-empirical g-functions are faster and allow easier analysis.
