Abstract

To develop a fast and reliable method for 3D steady state CFD simulation of large industrial circulating fluidized bed processes, new methods need to be developed. The most attractive approach seems to be time-averaged modeling that facilitates steady state simulation of fluidization. For model development and closure of the time-averaged equations, transient simulations can be utilized. The simulations presented here are done for that purpose. In CFB combustors, the suspension contains a wide variety of particles with different sizes, densities and chemical compositions, which also need to be taken into account in the modeling of the CFB hydrodynamics. Thus also mixtures of different particles were included in the present study.
