“…Its basic working principle is that the solidi particles are suspended from the bottom distributor of the receiver under the action of fluidized air drag force. The concentrated solar energy irradiates to the collector tube wall while the particles move from the bottom to the top under the transportation of gas to absorb the heat from the wall and then heated up to a certain temperature [63]. The upflow FB particle receiver offer several advantages including [32]: sufficient wall-to-bed heat transfer coefficient, homogeneous particles mixing, low energy losses, relatively high outlet temperature and easy regulated particle flow rate.…”

“…Results show that sensible energy storage delivers superior energy and power density (68 kWh/m 3 and 4.5 kW/m 3 ) as opposed to 26 kWh/m 3 and 1.8 kWh/m 3 for hydrogen energy storage, respectively. More details on the materials, configurations and methodologies of the gassolid fluidized-bed particle solar receivers have been reviewed and summarized by Jiang et al [118] and Tawfik [119].…”

A highly efficient receiver is required because re-radiation loss increases dramatically with increased working temperature. Among a large number of receivers, the fixed-bed Particle Solar Receiver (PSR) represents a new pathway to high temperature with maximum overall thermal efficiency. The incoming solar radiation can penetrate deeper into the fixed-bed PSR filled with semi-transparent quartz and ceramic particles (spheres or Raschig rings), resulting in an increased volumetric effect. Reports show that an optimized PSR can realize overall receiver efficiency of around 92% at outlet temperatures above 1000 K, and achieve the annual temperature above 1000 K over 65% annual operating hours integrated with a concentrated solar power (CSP) system. To fully understand radiative heat transfer characteristics and provide deep insight into thermal efficiency, radiation energy is classified as incident solar radiation and radiative heat exchange in two parts. The transfer mechanism, the solution method and the progress of the investigation for each section are summarized and discussed in detail. Then, challenges and future directions, including an innovative design method, an improved experimental approach and an effective simulation method are proposed to put forward this receiver to be a preferred substitute in advanced, high-temperature power cycles.

The efficiency and accuracy of the Euler‐Lagrange/discrete element method model were investigated. Accordingly, the stiffness coefficient and fluid time step were changed for different particle numbers and diameters. To derive the optimum parameters for simulations, the obtained results were compared with the measurements. According to the results, the application of higher stiffness coefficients improves the simulation accuracy slightly, however, the average computing time increases exponentially. For time intervals larger than 5 ms, the results indicated that the average computation time is independent of the applied fluid time step, while the simulation accuracy decreases extremely by increasing the size of the fluid time step. Nevertheless, using time steps smaller than 5 ms leads to negligible improvements in the simulation accuracy, though to an exponential rise in the average computing time.
