“…And the molten nitrate salt receiver technology in solar power tower plants has developed rapidly during this period. The downside is that the phenomenon of “hot spots” has arisen as a result of the uneven heating of the metallic tubular receiver, which poses risks to operational safety 66–68 . Therefore, the SPSR technology has once again received considerable attention, and various SPSR designs have been developed for positive particle flow control.…”

Solid particles are generally considered to be the most suitable heat transfer fluid (HTF) and thermal energy storage (TES) materials for the next‐generation concentrated solar power (CSP) plant. The operating temperature of the solar receiver can be raised to exceed 800°C by the application of appropriate solid particles. In this way, power conversion efficiencies greater than 50% can be achieved with the supercritical carbon dioxide (sCO2) Brayton cycle. Solid particle solar receiver (SPSR) is the key equipment to absorb the concentrated solar flux, and its thermal performance is remarkably affected by receiver system designs, particle flow characteristics, and properties of solid particulate materials. This paper provides an in‐depth review of various SPSR technologies, as well as pertinent solid particle selections, optimization of the receiver system structures, particle flow characteristics, and heat transfer characteristics. The technical drawbacks, the large‐scale development prospects, and the potential optimization strategies of the various SPSR designs are highlighted by the comparative analysis of multiple parameters.

“…However, as stated in Section 2.2, it is later recalculated so the entropy generation due to the heat conduction through the wall is minimized. The length of the tubes, Lt, is 10 m. Solar salt (60% KNO3, 40% NaNO3 ) is selected as the HTF in this receiver, as in the case of the commercial SPT plants [35,36]. The inlet temperature, 𝑇 𝑖𝑛,𝐻𝑇𝐹 , is 290 °C to avoid its freezing, while the outlet temperature, 𝑇 𝑜𝑢𝑡,𝐻𝑇𝐹 , is limited at 565 °C, preventing its decomposition [37].…”

“…The parabolic dish collector (PDC) is one of the main types of CSP systems. However, the concentrated solar flux distribution in the CSP system is extremely non-uniform, which causes local high temperatures and large temperature gradients in the receiver and seriously affects the safety performance and service life of the CSP system [ 7 , 8 , 9 ]. The typical problems include degeneration of the materials, thermal stress, deformation, and overburning [ 10 ].…”

The design of a thermal cavity receiver and the arrangement of the fluid flow layout within it are critical in the construction of solar parabolic dish collectors, involving the prediction of the thermal–fluid physical field of the receiver and optimization design. However, the thermal–fluid analysis coupled with a heat loss model of the receiver is a non-linear and computationally intensive solving process that incurs high computational costs in the optimization procedure. To address this, we implement a net-based thermal–fluid model that incorporates heat loss analysis to describe the receiver’s flow and heat transfer processes, reducing computational costs. The physical field results of the net-based thermal–fluid model are compared with those of the numerical simulation, enabling us to verify the accuracy of the established thermal–fluid model. Additionally, based on the developed thermal–fluid model, a topology optimization method that employs a genetic algorithm (GA) is developed to design the cavity receiver and its built-in net-based flow channels. Using the established optimization method, single-objective and multi-objective optimization experiments are conducted under inhomogeneous heat flux conditions, with objectives including maximizing temperature uniformity and thermal efficiency, as well as minimizing the pressure drop. The results reveal varying topological characteristics for different optimization objectives. In comparison with the reference design (spiral channel) under the same conditions, the multi-objective optimization results exhibit superior comprehensive performance.
