Abstract
Next generation concentrated solar power (CSP) plants are envisioned to use carbon coated particles like HSP 60/40 as a highly efficient heat transfer fluid. There has been previous work on the development of subcomponent models, but these existing models are complex and computationally expensive. The goal of this work is the development of simpler thermal models of a particle storage silo and a particle-to-super critical carbon dioxide heat exchanger. These models are then combined together into a continuous system where the particles flow from the storage system through the heat exchanger. Parametric studies are then performed on both the individual and combined components to test the impact of changing design and operational variables on the thermal response. The models are developed in a way for later use in system level CSP models.
