- •
An advanced gaseous tracer technique has been developed and utilized in this work.
- •
An axial dispersion model has been developed and used for the packed-pebble bed.
- •
A methodology that properly counts for the external dispersion has been applied.
- •
The axial dispersion coefficient depends on both gas flow rate and pebble size.
- •
This work advancing the knowledge of mixing phenomenon in the packed-pebble bed.
