Original Kurzfassung:
Iron-ore reduction has attracted much interest in the last three
decades since it can be considered as a core process in steel indus-
try. The iron-ore is reduced to iron with the use of blast furnace and
fluidized bed technologies. To investigate the harsh conditions in-
side fluidized bed reactors, computational tools can be utilized. One
such tool is the CFD-DEM method, in which the gas phase reactions
and governing equations are calculated in the Eulerian (CFD) side,
whereas the particle reactions and equation of motion are calculated
in the Lagrangian (DEM) side. In this work, this method has been
extended to cover the most common types of representation models
for the reactions of solids submerged in fluids. These models are
the Shrinking Particle Model (SPM) and the Unreacted Shrinking
Core Model (USCM). With the use of the SPM, the implemented
communication framework between the CFD and DEM sides have
been verified by running some preliminary cases and comparing the
species mass balances. In the modelling of iron-oxide reduction the
SPM is insufficient to represent the different reaction steps, there-
fore a three-layered USCM is utilized. The implemented USCM is
validated by running some preliminary cases.
