Summary: A pore-scale flow and heat transfer model is developed to investigate the thermal and hydrodynamic performance of a volumetric solar receiver under highly concentrated irradiation. Three-dimensional simulations are conducted based on the Weaire-Phelan structure modeling an open-cell ceramic foam absorber. The study predicts and compares the energy conversion characteristics of two ceramic materials (SiC and Al2O3). Various control approaches for the optical property of the solar absorber are introduced and analyzed. Results show that SiC absorber outperforms Al2O3 absorber and the optical property of the absorber front region significantly affects overall performance. Decreasing absorptivity and spectral selective design have positive impacts, with spectral selective improvement showing the highest effectiveness. Additionally, adding a porous fused silica as the front absorber layer effectively shifts the high-temperature area inward with a slight decrement in efficiency, and honeycomb structure exhibits advantages over foam silica.
