Effects of Volumetric Property Models on the Efficiency of a Porous Volumetric Solar Receiver

Energies, 2022
A porous volumetric receiver is the key component in concentrated solar power systems. In this paper, we investigate the effects of volumetric parameter models on the heat collection efficiency of the volumetric receiver by numerical simulations with the

VoCoRec - A novel two-stage volumetric conical receiver

AIP Conference Proceedings, 2023
At solar tower systems, open volumetric air receivers are attractive for electricity generation as well as for chemical and other industrial processes. In order to overcome inherent limitations within the previous lines of development, a fundamentally new receiver concept has been developed – the VoCoRec.
