bulk solids handling Journal Research Paper Rapid Poiseuilie Flow of Granular Materials We solve the problem of rapid Poiseuille flow of a granular material in a pipe. The material is viewed as an incompressible continuum with a stress given by a Reiner-Rivlin type constitutive equation. Two material parameters appear in the constitutive equation. The magnitude of one of these paramete…read more
