抄録

The radiation heat exchange between a fluidized bed and heated surface was investigated via an optical experiment employing a He-Ne laser and by corresponding numerical simulation analysis. A model for predicting the radiation heat transfer is subsequently proposed, which considers the thermal boundary layer near the heated surface. The numerical results indicate that radiation 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, with these results being in good agreement with radiation heat transfer measurements.
