- •
Layer inversion voidage can be directly predicted.
- •
Theoretical derivation shown for simple and improved polydisperse drag.
- •
Extensive comparison and validation against experimental data.
- •
Layer inversion maps can be calculated as function of size and density ratio.
- •
Expansion behavior and separate calculation of velocity also demonstrated.
