Modeling granular material blending in a Tote blender using a finite element method and advection-diffusion equation multi-scale model

摘要: Abstract A multi-scale model is presented for predicting the magnitude and rate of powder mixing in a Tote blender. The combines particle diffusion correlations calibrated from experiments with transient advective flow field information finite element method simulations. Predictions compare well quantitatively to published experimental data side-side top-bottom loading conditions. model, since it does not directly individual particles, expected scale systems industrial interest.
