An overview of research on particulate solids at Edinburgh
Abstract: Particulate solids are everywhere. These include salt, sugar, soils, mineral ores, agricultural grains, pharmaceutical powders and a very wide range of industrial solids. The behaviour of particulate solids and the issues relating to handling and processing are thus of interest to engineers and scientists working in many fields.
This presentation first describes some of the phenomena associated with the storage and handling of particulate solids. The studies conducted at Edinburgh to investigate two of these phenomena, namely silo honking and silo arching, are briefly described. Silo honking is a phenomenon in which the silo emits a loud intermittent “honk” similar to a truck horn when it is discharging. Silo arching is when the flow of stored solid is arrested due to cohesive bridging across the outlet. The presentation will discuss various aspects of the current research on particulate processes being conducted at Edinburgh, focussing on the discrete element modelling of cohesionless, cohesive and bonded granular materials.
