Abstract: This paper concerns solar-to-thermal energy conversion processes in an open cavity volumetric receiver for a 50-MWth integrated beam-down receiver-storage concentrating solar thermal system. A multiphysical model was developed in a COMSOL Multiphysics 6.1 environment. The model was validated against experimental and modelling data from the literature. The model incorporates specific solar irradiation profiles tailored …

Abstract: High–temperature solar reactors, which directly heat particle materials, are one of the promising paths leading to more sustainable industrial processes. In case of controlled atmosphere processes, the presence of a window could strongly increase the system efficiency. Nevertheless, so far, particle deposition on the window remains a challenge. This paper proposes an innovative solution …

Abstract A new optimization method was proposed to design high-performance deformable petal heliostat fields for concentrated solar power. The petal field was divided into individual sectors, each separately designed to balance pattern orderliness and flexibility. A suitable high-dimensional optimization algorithm was identified from 129 different algorithms using multi-algorithm filtering. To examine the proposed method, four …
