چکیده مقاله:
The use of ground as a heat source in geothermal heat pumps has been considered in recent years due to its high efficiency and energy savings. In this paper, the numerical simulation of the thermal performance of hybrid nanofluid flow in a horizontal geothermal heat exchanger equipped with twisted tape as turbulator is done using ANSYS Fluent CFD code. The results of numerical simulation were compared with experimental works and a good agreement was seen between the results. The results show that the horizontal geothermal heat exchanger has better heat transfer to the ground surface in the case with hybrid nanofluids than in the case with pure water.Keywords: Borehole Heat Exchanger, Twisted Tape, Hybrid Nanofluid, Turbulator, Heat Transfer, Thermal Performance.
