The radiative heat exchange between a fluidized bed and a heated surface was investigated via an optical experiment employing a He-Ne laser and numerical simulation analysis. A model for predicting the radiative heat transfer is proposed that considers the thermal boundary layer near the heated surface. The numerical results indicate that radiative heat transfer is enhanced when the penetration depth of radiation is greater than the thickness of the thermal boundary layer. This occurs because the radiation is effectively exchanged between the heated surface and low-temperature particles fluidizing outside the thermal boundary layer. These results are in good agreement with radiation heat transfer measurements.
