Perez, R. B.

Starting from Soo's basic multiphase equations, a set of one-dimensional time-dependent hydrodynamic and enthalpy equations was developed for a fluidized bed reactor by averaging over its cross sectional area. The following effects were not considered in the derivation of the FBC equations: forces to accelerate the apparent mass of the solid particle, basset force, heat exchange by radiation between solids and fluid or within each phase, and electrodynamic effects. Within these restrictions, the material developed here forms the basis for a sequel to this report devoted to the development of stability studies and to the application of stochastic methods for FBC surveillance.
