Conveying Characteristics of Pneumatic Conveyor : Part 2, Pressure Drop in the Bends

CFD Simulation of Gas-Solid Two-Phase Flow in Pneumatic Conveying of Wheat

Computational Fluid Dynamics (CFD) simulations of gas-solid flow through a positive low-pressure pneumatic conveyor were performed using Eulerian-Eulerian framework. Pressure drop in pneumatic conveying pipelines, creation and destruction of plugs along the horizontal and vertical pipes, effect of 90° elbows and U-bends on cross-section concentrations, and rope formation and dispersion were...

The Influence of the Pipe’s Material and the Mass Flow Rate on the Pressure Drop and Velocity Variation During Pneumatic Conveying of Wheat Using Computational Fluid Dynamics

According to flexibility of pneumatic conveying systems with respect to other types of transmission systems, this system has wide application in industry and agriculture processes. One important application of this system is in the loading and unloading tankers and powdery bulk materials such as trucks carrying cement, plaster and sand. Conveying efficiency is associated with pressure, which in...

Dilute-phase Pneumatic Conveying of Polystyrene Particles: Pressure Drop Curve and Particle Distribution over the Pipe Cross-section

During the pneumatic conveying of plastic pellets, it has been observed that materials with similar physical characteristics may develop a substantial difference in pressure drop. In this work, the pressure drop in a particle-laden 2.7 meter long horizontal channel with circular cross-section is presented from an experimental perspective. Experiments are carried out for cylindrical polystyrene ...
