Abstract:The particle velocity field and axial distribution of solid holdups in liquid-solid circulating fluidized beds have been simulated based on three-dimensional full Navier-Stokes(N-S) equations.Computational fluid dynamics(CFD) results implementing a Eulerian model with standard turbulence show that these type of simulations can give qualitatively reasonable agreement with experimental measurements.
Keywords:liquid-solid circulating fluidized bed  particle velocity  solid holdup
