Abstract

The Variations of hydrodynamic

heat and mass transfer behavior for systems of type B particles (according to Geldart s classification) with the addition of type A particles have been investigated. Based on experiments of more than twenty different systems composed of particles of FCC(A)

A12O3 (A). AN(B)and CA(B)

the correlations for the calculation of incipient fluidiza-tion velocity

incipient bubbling velocity and heat transfer cofficient of the bed to immersed surface have been obtained. Furthermore

a criterion for the classification of particle mixtures has been proposed

and the interphase mass transfer coefficients between bubble phase and emulsion phase have been determined and quantitatively analyzed.
