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...

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...

Abstract One objective for the 3rd Generation of Concentrating Solar Power technologies is to improve the efficiency of Central Tower, which is among the most promising solar concentration technologies. Central Tower Power Generation Plants are made up of hundreds of...

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...

Abstract Falling particle receiver (FPR) systems are a rapidly developing technology for concentrating solar power applications. Solid particles are used as both the heat transfer fluid and system thermal energy storage media. Through the direct irradiation of the...

Abstract: This study investigates the thermal performance of cavity-shaped porous solar receivers (C-PSR) designed to reduce peak solid temperature and re-radiation losses by optimizing the matching between the heat transfer fluid mass velocity and concentrated solar...

Abstract: An experimental and computational research was performed to explore the augmentation of turbulent convection in a solar receiver channel by utilizing louver-punched V-type winglets (LPVWs) that were fixed to the absorber plate. The simulation utilized the...

Abstract: Volume-averaging method constitutes an efficacious approach for analyzing and optimizing the overall efficiency of the porous receivers. However, the accuracy in the prediction of heat transfer process is significantly contingent upon the precise assessment...
