| Abstract: | By employing the Energy-Minimization Multi-Scale (AMMS) model, Siegen's modelfor the hydrodynandcs in a CFBC was improved. Based on the underlying mechanism, a new method to calculate axial voidage profile, upward and downward solid mass flux is proposed, which strength ens the uniformity of theoretical background of the model and makes it more analyticable. The comparisons between model predictions and experimental data indicated that the model is capable to describe the hydrodynamics in a CFB. |
