A Novel Imaging Methodology To Estimate Advective Losses From A Concentrating Solar Power Particle Receiver, Jesus Daniel Ortega
Mechanical Engineering ETDs
Falling particle receivers (FPRs) such as the one at Sandia National Labs, represent the state-of-the-art Concentrating Solar Power (CSP) technology for energy harvesting. The FPR operates by creating a gravity-driven particle curtain in a receiver that is irradiated by concentrated sunlight from a field of concentrators. The particles are used directly as the heat transfer and storage media for the concentrated energy absorbed. However, during operation, particles can egress through the open aperture of the receiver cavity, resulting in particle-inventory and heat losses from the system. The particle plumes egressing from the cavity present a unique challenge to metrology due …
