Common techniques for determining powder flowability [42].
| Method | Parameter being measured |
|---|---|
| Bed expansion ratio | Determines fluidized height against upstream fluid flow |
| Angle of repose (DIN ISO 4324) | Determines the pile angle |
| Ring shear cell (ASTM D 6773) | Determines shear force against normal pressure or compression rate |
| Revolution powder analyzer | Determines the avalanche angle |
