- •
The defluidization of fine glass particles is investigated via DEM–CFD simulations.
- •
Defluidization curves are sensitive to Young׳s modulus and static bed height for cohesive particles.
- •
The sensitivities are associated with the interaction of cohesive effect with material stiffness and packing structure during defluidization.
- •
Complete fluidization velocity is identified as a measurement that can be compared directly between small-scale simulations and large-scale scale experiments for model validation.
