Euler-Granular Approach for Modelling of Dilute Phase Pneumatic Conveying in a Vertical Pipe

摘要

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 dens ity of conveyed materials was 1020 kg/m 3 . Simulations f or 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.
