A Combined Experimental and Numerical Thermo-Hydrodynamic Investigation of High-Temperature Fluidized-Bed Thermal Energy Storage

The present research describes the design, analysis, and modeling of an air-granular particle fluidized-bed system with dimensions 0.08 m × 0.4 m. hydrodynamic thermal experiments are designed to verify numerical model previously created for this purpose. gas-solid two-phase flow is described using a three-dimensional, two-fluid based on Eulerian–Eulerian method. experiment conducted, updated new geometry while maintaining solution parameters. Silica sand sintered bauxite particles employed in both experimental investigations examine behaviors these particles. validity established by use findings pressure drop bed expansion ratio. tests conducted 585 K hot sand, temperature distribution measured K-type thermocouples compared simulation data. Both hydrodynamical data appear agree conclusions computational analyses. validated then used mimic performance at elevated temperatures. indicators discussed calculated 973 K, demonstrating that as rises, efficiency increases.
