This paper analyses the process of fluidization of mixtures of two spherical solids differing only in density and addresses the relationship between bed suspension and component segregation. It is shown that relating the progress of segregation to the excess gas velocity mu-mu(mf), a parameter that should represent the intensity of bubbling, gives way to serious errors, due to the fact that extending to binary beds the concept of minimum fluidization velocity leads to overlook some important aspects of their behaviour.

Abstract

This paper analyses the process of fluidization of mixtures of two spherical solids differing only in density and addresses the relationship between bed suspension and component segregation. It is shown that relating the progress of segregation to the excess gas velocity mu-mu(mf), a parameter that should represent the intensity of bubbling, gives way to serious errors, due to the fact that extending to binary beds the concept of minimum fluidization velocity leads to overlook some important aspects of their behaviour.
