CFD-DEM simulation of the pneumatic conveying of fine particles through a horizontal slit

- Pneumatic conveying of fine particles in a small scale horizontal slit was studied.
- Stratified, dune, pulsation and periodic plug flows were simulated with varying gas velocity.
- Horizontal gas velocity profile deviated from that of single phase turbulent flow.
- Vertical gas velocity fluctuated up and down.
- An overall voidage decrease or fluctuation was simulated.
