Abstract: Hypotheses are presented here for improving bulk solids flowability. They are directed toward a quantitative design goal for gas-solids flow systems. An effort is made to relate gas control in gas-solids flow systems to the Jenike design method. Cohesion and friction in slumped beds are frequent barriers to flow. Gas or liquid moving through bulk solids interstices can reduce interparticle cohesion. Changes in interstitial fluid pressure can modify friction angles and so change channel flow factors and bulk solid flow functions. Mass flow can be achieved in gas-solids flow systems using comparatively large hopper half apex angles.
