| 500 ## - GENERAL NOTE | |
| General note | Geothermal energy has been recognized as a reliable and continuous resource of<br/>renewable energy. In the past, numerous investigations have been conducted to increase<br/>the thermal performance of the coaxial borehole heat exchangers. Previous research<br/>efforts have focused on parametric studies, incorporated the use of vortex generators<br/>and multiple external chambers. While the effect of fins on various configurations, such<br/>as U-tube, spiral tubes and horizontal type heat exchangers have been studied, there is<br/>a lack of research on their impact on geothermal coaxial borehole heat exchangers. In<br/>this study the effect of longitudinal fins on coaxial borehole heat exchanger (CBHE)<br/>was evaluated using CFD software. Transient simulations were performed for the<br/>period of 24 hours for cooling operation at different flow rates i.e 4L/min and 8L/min.<br/>Fin lengths of 5mm, 10mm, 15mm and 20mm were evaluated to determine optimum<br/>fin length. At optimum fin length of 15mm, it was observed that heat transfer rate per<br/>unit length was increased by 18% at 4L/min and 22% in case of 8L/min flow rate which<br/>indicates the increase in CBHE efficiency. This research establishes a foundation for<br/>future investigations of finned ground heat exchangers which can contribute towards a<br/>sustainable and efficient energy solution.<br/> |
