Cover Story: The presented study focuses on evaluating the mixing properties of gyroid geometry and its modifications as advanced mixing elements in renewable energy technologies. Using numerical simulations, the hydrodynamic characteristics of the gyroid structure and five geometric modifications were analyzed under laminar flow conditions simulating the mixing of water and ethylene glycol. The evaluation was conducted using the parameters mixing index and performance index. The results show that all tested geometries significantly improve the degree of mixing compared to an empty channel. The results of the study demonstrated that, despite similar hydraulic losses among some of the structures, their fluid mixing performance differs, which highlights the importance of targeted geometric design of sheet-gyroid structures.
