Heat Transfer in Oxisol Soil During Geothermal Storage Process

Experimental data on heat transfer in a Red Latosol (Oxisol) soil during a geothermal energy storage process. The study used two linear heat exchangers (PVC and copper) across three temperature differentials, three radial distances, and three replicates. Soil temperature variations were logged continuously over a 12-hour period using DS18B20 sensors.

Use Cases

• Modeling soil temperature variation based on the temperature differential between soil and water, as identified as the main influencing factor.
• Comparing the thermal performance of different pipe materials (PVC vs. copper) for ground heat exchangers.
• Determining optimal spacing for heat exchangers based on radial distance measurements.
• Analyzing the logarithmic relationship between heat transfer time, radial distance, and soil temperature.

Strengths

• Experimental design includes a factorial scheme with three replicates, providing a structured basis for analysis.
• Data collection involved continuous temperature logging over a defined 12-hour period.
• Study investigates three concrete variables: temperature differentials (5, 10, 15 °C), materials (PVC, copper), and radial distances (10, 20, 25 cm).
