Proposal of a Novel Gravity-Fed, Particle-Filled Solar Receiver

Solar Thermal Electricity power plants utilizing solid particles as heat transfer and storage media have been proposed by several research groups, with studies citing benefits of increased thermal efficiency and lower cost. Several types of solid particle receivers have been proposed, with leading designs consisting of particles falling or suspended in air. A new solid particle receiver is proposed here, consisting of a receiver fully packed with particles flowing downward with gravity. Particle flow rate is regulated with an outlet valve. This Particle-Filled receiver concept is compared to other receiver designs, and initial cold and hot experiments are conducted. Mass flux values of up to 379 kg m-2 s -1 are demonstrated, and heat transfer coefficients between 136 and 251 W m-2 K-1 are found.


Investigation of mechanical and thermal properties of sintered bauxite and sand particles as heat transfer and storage media
Uykun, Zeynep; Tarı, İlker; Baker, Derek Keıth; Department of Mechanical Engineering (2021-1-11)
Solid particles have gained an attraction in recent years to be used as a heat transfer and storage medium that can be integrated into various thermal power plants. Particles operate in a closed-loop cycle in the power plants such as Concentrating Solar Power (CSP); firstly, they are heated up in the receiver then carried to the storage system and they discharge their energy to the thermodynamic-cycle. Discrete Element Method (DEM) has been gaining importance for modeling particle-based heat transfer and st...
Evaluation of hybridsolar-wind-hydrogenenergy system based on methanol electrolyzer
Budak, Yagmur; DEVRİM, YILSER (Wiley, 2020-10-01)
In this study, it is aimed to meet the annual electricity and heating needs of a house without interruption with the photovoltaic panel, wind turbine, methanol electrolyzer, and high temperature proton exchange membrane fuel cell system. The system results show that the use of the 2 WT with 18 PV was enough to provide the need of the methanol electrolyzer, which provides requirements of the high temperature proton exchange membrane fuel cell. The produced heat by the fuel cell was used to meet the heat requ...
Investigation of various options for numerical modeling of fluidized bedsI for a solar thermal application
Bilyaz, Serhat; Tarı, İlker (null; 2015-05-29)
Circulating fluidized bed solid particle absorption solar thermal energy system is a promising approach to solar thermal with thermal energy storage. For accurately modeling such systems, the fluidized bed numerical model should be correctly representing the behavior of the actual bed. There are several suggested partial semi-empirical models in the literature considering distinct phenomena related to fluidization and void fraction distribution in a fluidized be...
Numerical investigation of circulating fluidized bed riser hydrodynamics for concentrating solar thermal receiver applications
Bilyaz, Serhat; Tarı, İlker; Department of Mechanical Engineering (2015)
Various heat transfer fluids and thermal storage materials are considered for concentrating solar power systems to improve the storage capability of the system which compensates the fluctuating behavior of the solar resources. Solid particles can be a good alternative since they have high sensible heat capacity. In addition, they are cheap, environmentally benign and chemically and mechanically stable at high temperatures. In this thesis, hydrodynamics of circulating fluidized bed solar receiver was numeric...

Moia-Pol, Andreu; Pujol-Nadal, Ramon; Martinez-Moll, Victor; Bonyadi, Nima; Baker, Derek (2016-10-14)
The combination of solar thermal, photovoltaic, and heat pump technologies is a welcome advancement in countries with large solar resources such as Turkey. These systems could have similar efficiencies throughout the year for different locations in Turkey if we adjust the solar storage according to the weather conditions. In this paper, solar heating with a heat pump system for buildings have been designed to achieve different values of the fraction of primary energy saved using Flat Plate Collectors (FPC) ...
