In this study, two planar high-temperature solar receivers, equipped with Triply Periodic Minimal Surface lattices of Diamond and SplitP, were analysed numerically. These receivers were manufactured and experimentally tested in a previous study. Different RANS turbulence models, including Lag EB κ-ε, κ-ω SST (Menter), and Realizable κ-ε two-layer, were evaluated, and their results were compared with experimental data. A comprehensive validation revealed that the Lag EB κ-ε and κ-ω SST (Menter) models have the smallest deviation from the experimental data. The sample with the SplitP lattice demonstrated superior thermal performance with higher thermal efficiency, higher useful heat, and exhibiting a slightly lower maximum surface temperature and a narrower high-temperature region.
