Key findings
- Compares 5 TPMS geometries (Gyroid, Diamond, I-WP, Primitive, Lidinoid) against conventional Fins using 3D CFD.
- Per-geometry cyclic SCP: gyroid 379.3, diamond 393.6, Lidinoid 401.6 W/kg vs fins 357.4 W/kg.
- Lidinoid gives +12.4% SCP at fixed 500 s / porosity 0.5; +17.5% when each geometry runs its own optimal adsorption time.
- Primitive UNDERPERFORMS: -6.9% vs fins.
- Gyroid, Diamond, and Primitive show faster kinetics than Lidinoid and Fins.
- TPMS beats fins only at medium/high porosity (0.5, 0.8); higher porosity lowers SCP.
- Mechanism: the metal TPMS network raises effective thermal conductivity via its high surface-area-to-volume ratio.
- No TPMS-specific COP reported.
