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...

Pneumatic conveying, in which granular materials are transported using a gas phase, is an important industrial process for bulk particulate transport. This is usually carried out in either a dilute phase, in which the particles are effectively suspended in the gas phase, or a dense phase, in which the particles move in a bulk flow. Dense phase conveying is becoming increasingly popular as it re...

In a context of energy abundance for industrial applications, systems are exploited with minimal attention to their actual consumption requirements meet the loads imposed on them. As result, most them used at maximal capacity, regardless varying operational conditions. First, paper studies pneumatic conveying and thoroughly reviews previously published work. Then, we overview simulations operat...
