Determination of Effective Diameter of Solid Particles for the Eulerian-Eulerian Modelling Approach of Fluidized Bed.

Abstract

© 2019 IOP Publishing Ltd. All rights reserved. Theexperimental and numerical study of common used effective diameters for fluidized bed at a wide range of gas velocities was carried out. This work was motivated by Eulerian approach to modelling multiphase media. In the conditions of the experiments carried out and the Gidaspow drag model, the best agreement with the experiment was shown by the so-called modal effective diameter D mod. For minor gas velocities, the diameter D 32 was corrected in order to best coincide with the experiment.
