Research Interest


1. Analysis of heat trasnfer of large-scale clusters of pile and borehole ground heat exchangers

Ground heat exchangers (GHEs), also called geothermal heat exchangers, have emerged as a promising and globally accepted way of exploiting shallow geothermal energy (e.g., used in seasonal ground heat storage (GHS) and ground-coupled heat pumps (GCHPs)). Despite their great energy-saving potential, GHS and GCHPs have not yet been fully developed. This undesirable state is mainly due to difficulties in the design and analysis of GHEs, which involve complicated heat transfer calculations. The purpose of this study is to develop a theoretically complete frame for analyzing heat transfer of GHEs and provide an efficient tool for facilitating design of GHS and GCHP systems.

2. Entropy-based analysis and optimization of thermodynamic cycles and systems

Entropy-based analysis is an extremely powerful frame for analyzing energy systems. It is general enough and thus applicable for a wide spectrum of known and future applications. It can not only identify irreversibility occurred in thermodynamic systems but also provide key insights into the influences of working mediums on cycles and systems. Particularly, the entropy-based analysis can lead to analytical expressions for the performance and/or thermal efficiency of the considered systems. Entropy-based analysis, together with the method of entropy generation minimization, provides possibilities of optimizing thermal systems.
