Triply Periodic Minimal Surface (TPMS) heat exchangers have attracted significant attention for their high surface area and effective thermal performance. This study evaluates the performance of TPMS under turbulent flow conditions using aluminum (Al) silver (Ag) materials with pure water nanofluid as working fluids. The implementation Ag structures resulted in approximately 15% enhancement compared to Al due superior conductivity. introduction (0.6% volume concentration) improved overall transfer efficiency by 12% water. Performance evaluation criteria (PEC) analysis demonstrated that achieved up 30% higher values than structures. Temperature homogeneity analyses revealed improvements, showing a 24% reduction temperature variation when nanofluid, while exhibited 40% better uniformity. Computational fluid dynamics validated experimental findings deviations less 7%, confirming model’s reliability. These results demonstrate potential high-performance cooling applications provide valuable insights future exchanger designs. enhanced management system (TMS) nanofluids contributes reduced energy consumption, supporting environmentally conscious decision-making industrial systems.
