Gravity flow of granular materials in conical hoppers
Journal Article

· J. Appl. Mech.; (United States)
An approximate solution is presented to the problem of calculating the flow of a cohesionless granular material in a conical hopper such as that used in some coal gasifiers. Treating the material as a perfectly plastic continuum (thus satisfying the Mohr-Coulomb yield condition), the model describes the behavior of granular material in fairly good agreement with experimental data. Intended for application to a mass-flow hopper only, the model is most effective on hoppers with small hopper angles. The model and experimental results deviate at large hopper angles.
