Artwork: The impact hit with the energy equivalent to 10 billion Hiroshima bombs It is hard to imagine billions of tonnes of rock suddenly start to splosh about like a liquid - but that is what ...

Pyroclastic density currents (PDCs) represent some of the most formidable and complex volcanic phenomena, characterised by a turbulent mixture of solid particles and gases that surge down slopes at ...

The fluidisation behaviour of potato chips and cuboids in a 150 mm diameter vertical pipe has been investigated. The parameters studied include the quality of fluidisation, the friction factor and the ...

Segregation is a constant problem in industrial processes concerning bulk solids. It is generally either of a mechanical nature or a product of fluidization or pneumatic transport. The mechanical ...
