Developing Geothermal Energy Research Capabilities at University College Dublin

Hemmingway, Phil ; Long, Michael (Michael M.) (Geothermal Association of Ireland, 2011)

Ireland has one of the highest energy dependencies in Europe and as such must adapt quickly to increase renewable energy exploitation levels in order to secure its energy future. A mix of renewable energy technology types ...
The effect of groundwater flow on the thermal front created by borehole heat exchangers

Tolooiyan, Ali ; Hemmingway, Phil (OUP, 2012-12-21)

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 ...
Numerical and finite element analysis of heat transfer in a closed loop geothermal system

Hemmingway, Phil ; Tolooiyan, Ali (Taylor & Francis, 2013)

Analysis of the thermal regime created by a geothermal borehole heat exchanger is performed using a closed form radial heat flow equation, a geothermal borehole heat exchanger design tool and a finite element model. ...
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 ...
