Steady compressible flow of cohesionless granular materials through a wedge-shaped bunker
J. Ravi Prakash,K. Kesava Rao +1 more
TL;DR: In this paper, a continuum model based on the critical-state theory of soil mechanics is used to generate stress, density, and velocity profiles, and to compute discharge rates for the flow of granular material in a mass flow bunker.

Internal pressures in flowing granular materials from mass flow hoppers
V. Lakshman Rao,D. Venkateswarlu +1 more
TL;DR: In this paper, the internal pressure of perspex mass flow hoppers was studied using a radiopill receiving system. But the results were compared with the Jenike-Johanson theory, and the effects of stop/start operation and compaction of the fill material prior to the initiation of flow were also studied.

Pressures in hoppers filled with fine powders
P.G. Murfitt,P.L. Bransby +1 more
TL;DR: In this article, the authors used a mathematical model to describe the dissipation with time of these pore air pressures, and the model was used to scale up from a bench scale deaeration test to give the rate of air pressure dissipation in a large scale hopper, which was broadly in agreement with that observed.

TL;DR: In this article, a set of pyramidal and conical shaped hoppers of different apex angles, with rough or smooth walls and in some cases with vertical dividing walls, were used to measure the pressure of fine coal.
