In the present study, vertically upward dilute phase
pneumatic conveying flow was predicted using Euler-
Granular method. Three dimensional computational
fluid dynamics simulations were carried out for an 8 m
long and 30.5 mm diameter circular pipe. The density of
conveyed materials was 1020 kg/m3. Simulations for
different particle diameters; 200 µm and 500 µm were
performed. The air velocities ranged from 9 to 17 m/s
and solid to air mass flow ratios ranged from 0.0 to 3.8.
Pressure drop, air and particle velocity profiles and solid
distribution profiles were studied and some of the results
were compared with experimental data from existing
literature. Predicted pressure drop and air velocity
profiles are in good agreement with experimental
results.
