The main aim of this Lancaster University-Bradford University collaborative project is to understand the forces between a variety of dry materials at the single particle level, to relate these to the complimentary bulk powder flow measurements, and hence assess how far such single particle data are able to predict flow behaviour of real value to chemical engineers. In particular, we are interested in (a) the role of ambient conditions such as relative humidity, and properties such as particle size, roughness and surface condition, and (b) the role of both particle-particle interactions and particle-wall interactions, in flow and adhesion behaviour.
