Simulation of a Fluidized Bed Using a Hybrid Eulerian-Lagrangian Method for Particle Tracking
The characterisation of fluidized beds still requires specific investigation for understanding and modelling the local coupling between the dispersed phase and the carrier fluid. The aim of this work is to simulate this type of unsteady particle laden flows via Direct Numerical Simulations in order to provide a local and instantaneous description of particle flow interactions and to extract statistical parameters useful for large scale models. A fluidized bed has been studied experimentally by Aguilar Corona (). In this laboratory experiment, 3D tracking of a single bed particle provided Lagrangian properties of the discrete phase motion, while 2D PIV was used to characterize the flow of the continuum phase. This fluidized bed has been simulated during nine seconds in order to compare experimental and numerical results and to obtain some data that experimental studies can’t give.
