Solved Equilibrium centrifugation occurs when the sample
ResultPart A: Equilibrium centrifugation occurs when the sample density gradient reaches equilibrium in a centrifugal field. Because the sample is at equilibrium, transport of mass ceases. For this reason, unlike velocity sedimentation, equilibrium centrifugation measures the molar mass M2 but not the coefficient of friction.

Gas–solid fluidization in a centrifugal field
ResultAbstract. The nature of fluidization and the behavior of particles in a centrifugal field are discussed. Powders are classified into four groups (A, B, C, and D) following Geldart based on their fluidization behavior. A simple general model, agreeing with conventional fluidized beds and usable for variable "g," is proposed …

Fundamentals of a centrifugal fluidized bed
ResultA fundamental theory based on the local momentum balances is proposed to explore the fluidizing phenomena of a centrifugal particle bed. Unlike the conventional vertical bed, a centrifugal bed is predicted to be fluidized layer by layer from the inner free surface outward, in a range of aeration rates. The span of this range …
