✦ Synopsis

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 turbulence.

Results of calculations based on the model, for a two‐dimensional bubbling bed, indicate that a single bubble, having a diameter equal to the cylinder diameter, has a relatively small influence on the total heat transfer.

## Abstract Fluidized beds are particularly favored as chemical reactors because of their ability to exchange heat through immersed heat‐exchange surfaces. However, little is known about how the heat‐exchange process works on a single‐particle level. The most commonly applied theory of fluidized be
