Analysis of the Efficiency of a Borehole Heat Exchanger with Longitudinal Ribbing

Research output: Contribution to journalArticle


© 2017 Springer Science+Business Media, LLC The technique of calculating the heat engineering characteristics of a tube-in-tube type heat exchanger has been refined by using experimental data on heat transfer and hydraulic resistance of a ribbed tube in an annular channel. An analysis of the efficiency of a borehole heat exchanger on the basis of various criteria is carried out.
