Flow Characterization in Triply-Periodic-Minimal-Surface (TPMS)-Based Porous Geometries: Part 2—Heat Transfer

Transport in Porous Media, 2023
Abstract A complex heat transfer takes place between the solid matrix and the fluid within its pores and generally two types of assumptions are widely used for macro-scale modelling of heat transfer: local thermal equilibrium (LTE) when the solid and fluid phases are at the same temperature, and local thermal non-equilibrium (LTNE) when the ...

Modular Critical Element Recycling Platform Using a Nanoporous Additively Manufactured Gyroid

Advanced Engineering Materials, EarlyView.
A modular recycling platform integrates 3D‐printed nanoporous gyroid structures to enable efficient critical element recovery. This system utilizes a hierarchical architecture, combining macroscopic channels with polymerization‐induced nanoscale porosity. By systematically tuning structural wall thickness and resin formulation, the platform achieves an
