Study on Flow and Heat Transfer Characteristics Inside High-Porosity Open-Cell Copper Foams
International Journal of Heat and Fluid Flow · Elsevier · 2024 · Vol. 109, Article 109497 · Peer-reviewed · SCI-indexed
Definitive 2024 experimental and numerical study of open-cell copper foam thermal performance. Critical finding: convective heat transfer capacity of copper foam-filled channels is approximately 5–100 times greater than unfilled channels of the same size (citing multiple independent experimental validations). Documents that copper foam with porosities 40–98% shows interconnected network structure that enhances heat transfer through flow disturbances. At Re=300+, 48% increase in heat transfer vs channels without foam. Directly validates PrometheanFoam's 10–30 PPI sheet specifications for heat exchanger and data center heat pipe applications.
Influence of Copper Foam on the Thermal Characteristics of Phase Change Materials
Energies · MDPI · February 2023 · DOI: 10.3390/en16041994 · Open Access · Peer-reviewed
Experimental and numerical study of copper foam (15% volume fraction) embedded in paraffin PCM. Results: copper foam enhances thermal conductivity, reduces PCM melting time (870 seconds for composite vs pure paraffin). Simulation of 5 copper foam structures (Kelvin, Gyroid, IWP, Primitive, Hollow hexahedral) — all structures show improved heat transfer vs pure PCM. MDPI Sustainability 2025 follow-up confirms copper foam reduces heat storage time by 16.7% and heat release time by 14.7%. Directly validates PrometheanFoam's copper foam sheets for battery thermal management and thermal energy storage applications.
Copper Foam Reinforced Polymer-Based Phase Change Material Composites for Lithium-Ion Battery Thermal Management
Journal of Energy Storage · Elsevier · 2023 · Peer-reviewed
Copper foam (98% porosity) filled with composite PCM for lithium-ion battery thermal management: CF/CPCM-90 thermal conductivity improved to 0.943 W/m·K — nearly 3× higher than CPCM without copper foam. Battery temperature maintained below 60°C for 70 minutes at 7W heat generation (vs significantly shorter without CF). CF/CPCM duration below 60°C is 3× longer than copper foam alone and 4× longer than control group. Mechanical stability: withstands 2 MPa stress with only 1% strain. Validates PrometheanFoam's 85–92% porosity copper foam sheets (5–15mm thickness) for EV battery pack thermal management applications.
Copper Foam Electrodes for Increased Power Generation in Thermally Regenerative Ammonia-Based Batteries
Industrial & Engineering Chemistry Research · ACS Publications · Peer-reviewed
Direct measurement of copper foam electrode performance vs standard copper plate electrodes: copper foam incorporation leads to 38% increase in maximum power compared to copper plate. Optimal thickness for maximum power and energy density: 10mm copper foam (directly matching PrometheanFoam's 10–15mm sheet tier at 15–20 PPI). Stable electricity generation over 14 discharging batch cycles (>28 hours) with maximum power maintained at 58 ± 5 mW. Validates PrometheanFoam's ultra-thin rolls (100–130 PPI, 350–550 g/m²) for battery electrode current collector applications requiring high surface area.
