Experimental study of a novel downhole heat exchanger utilizing working fluids for enhanced heat exchange

Case Studies in Thermal Engineering
This study designs and assesses a new type of shell and tube downhole heat exchanger (NDHE) equipped with organic working fluid (R32, R134a) to increase the thermal performance of the single well geothermal system.
