A “particle-based” heat transfer model is proposed in order to predict the radiative contribution to the total wall-to-bed heat transfer for intermediate particles (600 < dp<1500 μm).A discussion about the heat transfer surface and the gas film thickness is presented. The present solution is compared with previous ones. The predicted radiative contribution increases with temperature, particle diameter and emissivity. At bed temperature Tb= 900°C, the radiative contribution rises from 9% to 17% when the Al2O3particle diameter varies from 0.73 to 1.4 mm (εp= 0.4), it reaches 18% and 33% respectively for black particles (εp= 1). Present results are compared with literature data. It is shown that “packet” and “particle” models are complementary. |
