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
Part 1 of this contribution reported on the effects of system properties on heat transfer between heating or cooling surfaces and bubbling fluidized beds. This investigation produced four correlations which define the respective maximum heat transfer. Part 2 of this study suggests that the heat tran
## Abstract Fluidized beds are particularly favored as chemical reactors because of their ability to exchange heat through immersed heatβexchange surfaces. However, little is known about how the heatβexchange process works on a singleβparticle level. The most commonly applied theory of fluidized be
Abstraet-Fluid-particle heat transfer in lixed and fluid&d beds is re-examined. The heat transfer factor depends not only on the particle Reynolds number but also on the void fraction of the bed. The available experimental data has been correlated to yield a non-linear relationship between rJh and t
