| Abstract Scope |
Triply Periodic Minimal Surface (TPMS) architectures are promising candidates for compact heat exchanger applications. In this study, the thermal and hydraulic performance of a Fischer-Koch S (FKS) TPMS-based heat exchanger with a 15×15×15 mm³ unit cell and 50% volume fraction were investigated. The heat exchanger was fabricated via Laser Powder Bed Fusion (L-PBF) using AlSi10Mg alloy. Conjugate heat transfer simulations in ANSYS Fluent were validated against experimental tests using a purpose-designed apparatus. The convective heat transfer coefficients, static pressure distribution, fluid temperature profiles, and friction factor of the FKS topology were systematically quantified. The combined numerical and experimental results reveal a favorable balance between hydraulic efficiency and thermal performance and confirm that the L-PBF process successfully reproduces the complex FKS channel architecture with sufficient geometric reliability. This study shows that unit cell topology is a critical independent design parameter for simultaneous thermal and hydraulic optimization in compact TPMS-based heat exchangers. |
