Flow Characteristics and Particle Size Distribution in Pneumatic Conveying with Attrition

Introduction This work presents an analysis of gas-solids flow in a pneumatic conveying line wherein by collisions with the wall, the particles undergo breakage. A measure of particle attrition, the often-undesirable damage to particles, is necessary for design of many fluid-particle operations. For example, proper design of cyclones requires knowledge of the amount and size of fines produced f...

Particle velocity and concentration characteristics in a horizontal dilute swirling flow pneumatic conveying

An experimental study concerning particle behaviors in a horizontal dilute swirling flow pneumatic conveying was performed. Measurements of particle velocities and concentration profiles have been carried out using the photographic image technique. From the experimental results, it is found that mean particle velocity of swirling flow pneumatic conveying is lower than that of conventional pneum...

The Role of Particle Shape in Pneumatic Conveying

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...
