Numerical investigation of the hydrodynamic of a sand fluidized bed designed for heat storage

Résumé

The purpose of the present work is to study the capability of a sand fluidized bed system to perform as a heat storage. The focus is put on the numerical investigation of the main design criteria of the sand fluidized bed behavior, and the hydrodynamic aspect of the problem has been studied using a commercial CFD code. At first, the fluidized bed head losses which is a relevant design criterion is studied. The findings are compared with experimental data collected in the literature to approve the simulation. When the solid phase properties are set, the head loss depends on the on the fluid mean velocity and on the bed's height. The numerical tests were performed for fluid's mean velocities that are higher than the minimum fluidization velocity, and it comes that the simulated and the experimental data are similar.
