Conveying Characteristics of Pneumatic Conveyor : Part 1, Pressure Drop in the Pneumatic Conveyance of Granular Solids through a Straight Pipe

On the Electrostatics of Pneumatic Conveying of Granular Materials

In this work the electrostatics of the pneumatic conveying of granular materials in a non-conducting (PVC) vertical pipe is studied using Electrical Capacitance Tomography (ECT) system. The non-conducting wall in general attains static charges arising from particle-wall collisions in the initial periods of conveying process and then reaches equilibrium with the surroundings. The polarity of par...

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 ...
