Abstract

In this work, three-dimensional numerical simulations of a lab-scale pressurized fluidized bed are performed using an Euler-Lagrange approach. The gas phase is modeled in a LES framework, and the solid phase is tracked by the Discrete Element Method (DEM). The numerical predictions of the mean particle velocity are compared with experimental data obtained from Positron Emission Particle Tracking (PEPT). Results from Euler-Lagrange numerical simulations (LES-DEM) are compared with the predictions obtained using a Two-Fluid Model (TFM). The main goal of the present study is to carry out a statistical analysis based on the Mesoscopic Eulerian Formalism (MEF) in dense regime. One-point against two-point correlations are computed and the characteristic scales of the mixture are analyzed.
