Description

This study explores the thermal performance of three Triply Periodic Minimal Surfaces (TPMS) within a square duct: Gyroid, Helix Spiral, and Twisted Wave. The duct features a constant heat flux applied to opposite sides, with one end insulated, and fluid flows through the longitudinal section at a Reynolds number (Re) of 845,000. The primary focus is on evaluating the heat transfer enhancement and thermal performance factor (TPF). The heat acquired by the fluid (Q ratio) and the TPF were measured to assess the effectiveness of each surface in improving thermal performance. Results indicate that the Helix Spiral (TPF:0.77, Q ratio: 5.76) configuration achieved the highest heat transfer enhancement, followed by Gyroid (TPF: 0.75, Q ratio: 4.59) and Twisted Wave (TPF: 0.72, Q ratio: 3.9) . These findings highlight the potential of TPMS structures in optimizing thermal management systems, with the Helix Spiral emerging as the most effective design for heat transfer applications. This research provides valuable insights into the thermal performance of various TPMS geometries, offering a foundation for future advancements in heat exchanger design.
