Title

HYDRODYNAMIC CHARACTERISTICS OF DENSE CONICAL FLUIDIZED BED: CFD SIMULATION AND EXPERIMENTAL VERIFICATION

Pages

  42-59

Abstract

 The hydrodynamic characteristics of dense conical fluidized bed were investigated experimentally and numerically. Experimental studies have been carried out in a bed containing TiO2 particles belonging to A/C boundary of Geldart's classification with a wide particle size distribution. Pressure measurements and an optical fiber technique allowed determining the effect of high bed particles loading on the minimum fluidization velocity, local solid volume fraction and solid velocity. Two-fluid model approach with three different drag models and boundary conditions (BCs) consisting of no-slip, partialslip and free-slip BC is presented for the numerical predictions. In this paper, we show the Gidaspow drag function with k-e turbulent model by applying the partial-slip BC can improve the numerical results at high particle loading.
