Experimental study on convective heat transfer of an open-loop borehole heat exchanger
Abstract Open-loop borehole heat exchanger (OBHE) is a single well geothermal heat exchanger with an open-loop structure that can realize the geothermal energy extraction without mining the geothermal water.In this paper, a sandbox experiment redken shades eq 07m driftwood is designed to simulate the convective heat transfer process in the reservoi
