Aerated Flow of Powders

This report is the annual statement of progress on the Loughborough powder flow project. The project concerns the aerated flow of powders, that regime of flow where the voidage of the bed increases and the resistance of the powder to flow is greatly reduced. This investigation is a broad topic and may be considered to have three broad perspectives:

• Measurement of aerated flow of properties
• Manipulation of material properties and behaviour
• Behaviour of materials in engineering situations
