TLDR
In this article, the conductive and radiative heat transfer to the walls of a Fluidized Bed Combustor is calculated based on a gas film-emulsion packet model, where coal and ash particles are assumed to be spherical and the bed is considered to be vigorously bubbling.About:

A State-of-the-Art Review of Gas-Solid Turbulent Fluidization
TL;DR: Turbulent fluidization has been widely recognized as a distinct flow regime for the past two decades, even though it is commonly utilized in industrial fluidized-bed reactors due to vigorous gas-solids contacting, high solids hold-ups (typically 25-35% by volume), and limited axial mixing of gas as mentioned in this paper.

Mechanism of heat transfer to fluidized beds
H. S. Mickley,D. F. Fairbanks +1 more
TL;DR: In this paper, the heat transfer coefficients obtained with fluidized beds are found to be proportional to the square root of the thermal conductivity of the quiescent beds, which indicates that the process controlling fluidized heat transfer may be considered to be an unsteady-state diffusion of heat into mobile elements of quiesent bed material.

Study of radiative heat transfer in a fluidized bed
TL;DR: In this paper, the radiative component can be measured with the aid of two radiometer probes, and experimental data for bed temperatures up to 1700° K are presented as functions of the principal hydrodynamic and thermal parameters.
