- It compresses like a gas:
- It flows like a liquid:
- It is made up of small pieces of solid.
As a collective, particulate materials make up a new state of matter with unique properties and behaviors.
Why do we care how particulate materials behave?
We build on particulate materials:
Particulate materials are part of many manufacturing processes:
We need to know how to mix it:
separate it
transport it
Drive on it, build on it,
Example particle problems:
hopper flow
Multi-phase flow in pipe lines
Shock wave propagation
Fluidized bed
Ball Mill
Understanding natural phenomenon such as avalanches - fingering
slope stability and landslides
Brazil nut effect
How to model it:
Discrete element simulations:
How to solve particulate problems:
Break it down into the simplest components
