The ease with which air can flow through a powder bed reflects the strength of particle-particle interactions, and specifically highlights cohesive interparticle forces. Because air accounts for a large volume fraction of any bulk solid, specific characterization of powder-air interactions can lead to improved understanding of packing behavior in bulk solids and flow of bulk particles in process.
Powder-air interactions will directly influence: drying, coating, pneumatic conveying, fluidized beds, dry powder inhalers, and more. Because powder-air interactions are strongly correlated with powder cohesion and cohesive behavior, this is also an effective tool to generally understand powder rheology phenomena such as flow, shear, and consolidation.
