Year: 2024
Type: article
Abstract: In the field of scientific exploration, this study delves into the captivating realm of ground heat exchangers (GHE) by investigating the impact of rectangular protrusions strategically incorporated at the base of these systems.As vital components within geothermal systems, GHEs are responsible for efficiently transferring of thermal energy between the earth and the working fluid.However, through the ingenious integration of rectangular protuberances, the convective heat transfer dynamics within GHEs can be skillfully manipulated, potentially leading to remarkable enhancements in the heat exchange process.The maximum percentage increase in the heat transfer rate reached 23% at a distance of 2,500 meters, emphasizing the importance of strategic positioning of the protrusions.The primary objective of this research endeavor is to comprehensively examine the effects of these protrusions on the extracted temperature of the injected working fluid, thus yielding invaluable insights for optimizing GHE performance and advancing of geothermal energy utilization.
