The effect of groundwater flow on the thermal front created by borehole heat exchangers

Tolooiyan, Ali ; Hemmingway, Phil (OUP, 2012)

This paper presents an analysis performed using a coupled TEMP/W-SEEP/W finite element model to consider both the conducive and convective effects of groundwater flow on the thermal regime created by a ground source ...
Thermal response testing of compromised borehole heat exchangers

Hemmingway, Phil ; Long, Michael (Michael M.) (Oxford University Press, 2012-03-19)

The results of five thermal response tests (TRTs) are presented. Three of the tests were carried out consecutively on the same borehole to illustrate the importance of allowing artificially imposed thermal gradients to ...
