- •
Scale-up and hydrodynamics of gas-solid spouted beds are investigated.
- •
The common scale-up methodology for spouted beds is based on a set of dimensionless groups.
- •
This methodology is evaluated in this study using advanced non-invasive Radioactive Particle Tracking (RPT) technique.
- •
Two different sizes of spouted beds with matched and mismatched dimensionless groups were used.
- •
The results illustrate that the above method is not adequate to achieve hydrodynamics similarity between the two beds.
