Prediction of two hydrodynamic models and four entirely empirical correlations for the expansion of freely bubbling fluidized beds are compared with four sets of the experimental data. The results provide answers to some practical questions regarding the applicability of the recently proposed relationship for predicting the expansion in the fluidized beds with larger particles.
