文摘
- •
A volume-averaged momentum equation of a unique form for particulate flow was derived.
- •
Interaction force was modelled based on some theoretical solutions for uniform and shear flows.
- •
The interaction force model reasonably reproduced the energy transfer and the flow field around a particle.
