Packed Bed Modelling for CFD Simulations of Pellet Combustion
摘要：The work presented is part of a project that aims towards a deeper understanding of various pellet properties on the process of pellet combustion by means of test runs and simulations. A new transient CFD model for pellet combustion and packed bed compaction due to pellet shrinkage is described in detail and comparisons of the simulation results with the results from dedicated lab-scale reactor test runs are presented. The correspondence between simulated and measured mass loss, temperature and species concentration trends is well agreeable, however, space for improvement with regard to the velocity of charcoal burnout is still left.
