A physically based model is proposed for heat transfer to immersed surfaces in large particle fluidized beds. ' Large' particlesare distinguished as those with thermal time constants substantially greater than their residencetime at a heat tran sfersurface. At typical fluidized bed combustor operati
## Abstract A steady gas convection model of heat transfer to a horizontal cylinder immersed in a large particle gas fluidized bed has been developed. The model is based upon the hypothesis that the large particles will be isothermal and includes the effect of radiation as well as interstitial turb
