A short recent review on geothermal energy piles

Abstract

This manuscripts presents a short recent review of geothermal energy piles, emphasizing their problems, design elements, heat transfer fluids, and classification. Phase change materials (PCMs) are used as heat transfer fluids, and their beneficial effects on energy pile performance are highlighted. Design factors for the best energy pile performance are examined, including the usage of nanofluids and geometrical optimization. The analysis presented provides brief insightful information about the state of geothermal energy piles heaps now, laying the groundwork for future studies and advancements in this area.
