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...
متن کاملOn 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...
متن کاملThe 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...

متن کاملBulk Density of Granular Materials During Processing
Bulk density is an important process parameter for machines that transport, feed or process granular materials. Certain process variables have been shown to increase bulk density, such as the channel geometry at machines with rotational helical elements, the shape, dimensions and dimension distribution of granules, pressure, temperature, and vibration of the granular layer. The effect of the ra...
