dc.description.abstractFluidization experiments were performed by using spherical and non-spherical particles to examine the sensitivity of the variational model to three input parameters: U-mf, epsilon(mf) and U-t. Several correlations for U-mf, epsilon(mf) and U-t were tested and the results were compared with the experimental values. The variational model's ability to predict the bed expansion (in the form of U = f(epsilon)) and the interphase drag coefficient was investigated by varying the three input variables by +/- 20% compared with their experimental values. The variational model for the bed expansion showed the greatest sensitivity to changes in the epsilon(mf) values. The overestimated values of epsilon(mf) resulted in underestimating U(epsilon), and likewise, the underestimated values of epsilon(mf) resulted in overestimating U(epsilon). The variational model's sensitivity to changes in the U-mf values is also important. Contrary to epsilon(mf), overestimating the values of U-mf resulted in overestimating U(epsilon). The model's least sensitivity was to the U-t value variation, which, if varied by +/- 20% compared with their experimental values, had a negligible effect on the prediction quality. This study aims to examine the sensitivity of the variational model to U-mf,U- U-t and epsilon(mf) values obtained from various correlations, in the absence of experimental values.en
