Abstract: Flow through orifices has been investigated thoroughly and a large amount of information on discharge coefficients and losses is available. Almost all of these results presuppose that the ...

Abstract: Detailed observations of funnel flows of dry granular materials in wedge-shaped hoppers of different geometries are presented. The variations of the flow regime with changes in the height of ...

Abstract: Shear flows of granular materials are studied in an open channel. The wall shear is calculated from an open channel momentum equation which includes the density variations in the flow. An ...

Abstract: Local heat transfer and friction coefficients were measured in a circular tube for suspensions of bentonite and for a combination of bentonite and polyacrylamide in water. Both the entrance and ...

Abstract: An approximate solution to the flow of a cohesionless granular material in a conical hopper is presented. The material is modeled as a perfectly plastic continuum which satisfies the Mohr-Coulomb ...
