The temperature profile, total emissivity, flux density distribution, and effective mean penetration distance were determined from measurements in high‐temperature solar fluidized beds. A theoretical model is proposed to describe the complex heat transfer phenomena in the radiation penetration zone of the fluidized layers. The results correlated well at incipient fluidizing conditions for beds of silicon carbide and chamotte but were found imprecise for beds of zirconia and silica sand.
