Three numerical methods were compared to experimental data of a cold flow spouted fluidized bed.

Two-fluid model was able to predict the flow pattern for the small mass flow rate.

Euler–Lagrange MP-PIC and two-fluid methods were more appropriate for macroscale applications.

Euler–Lagrange DEM was more appropriate to catch flow pattern details at different mass flow rates.
