Sugar powder flowability

Peleg (1978) mentions that the characteristic compressibility can be used as a parameter to indicate flowability changes, because compressibility (Equations 13 15) has been related to cohesion C. The more compressible a material is, the less flowable it will be (Carr, 1965). This relationship has been found from experiments on limestone, powdered sugar, semolina, and flours at different particle sizes, size distributions, and moisture contents.
