Abstract

Numerical simulations based on a three-dimensional (3D) Eulerian-Eulerian multiphase model (two-fluid model, TFM) were carried out to study the minimum spouting velocities of scaled up spouted beds. The spouted bed with a diameter of 0.152m from the experiments of He et al. was scaled up by factors from 2 to 8, resulting in diameters from 0.304 to 1.216m. The effects of the static bed height, particle diameter, particle density and fluid inlet diameter on the minimum spouting velocity in different size beds were numerically investigated. A new empirical correlation is proposed for predicting the minimum spouting velocity in both small and large beds.
