One dimensional thermal analysis of silicon carbide ceramic foam used for solar air receiver

Synthesis and Characterization of Silicon Carbide in the Application of High Temperature Solar Surface Receptors

“…Due to its high absorptance values, superficial area, porosity and high fusion point (4), and its good thermo-mechanical properties (5,6) at high temperatures, SiC presents great advantages for applications in solar receptors used in a central tower plant, having a positive impact on the efficiency of the processes of electrical energy production (6)(7)(8). The receptors used in central tower plants usually working from 500°C and above 1000°C (2), at this temperature, the required materials must be able to endure not only everyday use but also long periods of time maintaining its properties and characteristics.…”

Heat Transfer Performances and Exergetic Optimization for Solar Heat Receiver

“…The heat transfer media in solar thermal power plant mainly include water/steam (Zarza et al, 2004), molten salts (Reilly & Kolb, 2001) and air (Bai, 2010), etc. In order to analyze the heat transfer performance of solar heat receiver in detail, the heat transfer media are assumed to be Hitec heat transfer salt and air in present article.…”

Dynamic simulation and experimental validation of an open air receiver and a thermal energy storage system for solar thermal power plant

“…Some studies were from a macro-perspective based on certain simplifying assumptions. Bai [20] investigated the heat transfer in ceramic foams in solar air receivers based on a one dimensional physical model. Wu et al [21] and Xu et al [22] analyzed the temperature distributions in the fluid and solid phases in ceramic foam air receivers for various porosities, average particle diameters, air inlet velocities, and absorber thicknesses using two dimensional numerical models.…”
