The presented study focuses on evaluating the mixing properties of structures derived from so-called sheet-gyroid geometry and their modifications as advanced elements in renewable energy technologies. Using numerical simulations based computational fluid dynamics (CFD), hydrodynamic characteristics basic structure five geometric were analyzed under laminar flow conditions simulating water ethylene glycol. evaluation was conducted using parameters index performance index, which express efficiency homogenization its associated demands. results show that all tested geometries significantly improve degree compared to an empty channel. highest concentration homogeneity best achieved by twisted structure. This modification exhibits value confirming ability achieve excellent with minimal pressure losses. demonstrated that, despite similar hydraulic losses among some structures, differs, highlights importance targeted design structures. These findings are essential for efficient mixers technological applications where intensive combined consumption is a critical factor.

Thermal protection systems play a pivotal role in astronautical engineering fields. However, traditional rectangular fin (RF) structures exhibit low thermo-fluid properties. Inspired by the minimal surfaces nature, this study develops three types of triply periodic surface (TPMS) lattices, namely, sheet primitive (SP), network I-WP (NW), and (SW) using mathematical formulae. The TPMS lattices are fabricated laser powder bed fusion AlSi10Mg powder. A convective heat transfer simulation model is established validated through experiments. fluid flow characteristics, overall performance comprehensively investigated based on model. Results show that relationship between pressure loss velocity satisfies Darcy–Forchheimer law. Compared to RF structures, more uniform temperature distribution at same rate, highest coefficient increased approximately 96.62%. This due complex internal which enhance disturbance further improve coefficient. thermal index (α) higher than with an order αSP>αSW>αNW>αRF, confirms potential applications systems.
