Analysis on performance of borehole heat exchanger in a layered subsurface

Luo, Jin; Rohn, Joachim; Bayer, Manfred; Priess, Anna; … - In: Applied Energy 123 (2014) C, pp. 55-65

In the current design of borehole heat exchangers (BHEs), the ground is commonly considered to be homogenous. However, in a layered subsurface, thermal performance of BHE can deviate drastically with different strata. Thereby, analysis of the heat transfer of a BHE with different geological...
