Mathematical simulation of the aerodynamics and heat-and-mass transfer in a circulating fluidized bed

A mathematical model describing mass, momentum, and heat transfer in units having a circulating fluidized bed (CFB) is proposed. A numerical algorithm based on this model enables us to calculate the averaged characteristics of the process that are important for designing and obtaining a detailed picture of the multifractional disperse system in a CFB, in particular, in steam boiler furnaces.
