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...

Numerical Simulation of Dense Phase Pneumatic Conveying in Long-Distance Pipe

Computational Fluid Dynamics is now a new ramification of the numerical discretization method based on high-performance electronic computers, which focuses on fluid mechanics simulation. Fluid mechanics has two main braches that one is theoretical analysis and another is experimental research. Therefore, theoretical and experimental fluid mechanics were created as most important constituents in...

Pneumatic Conveying System: an Overview

3 Design engineer, Scorpio, Industries ltd., (India) ABSTRACT Pneumatic conveying system has always been economic and efficient means of conveying materials. From the historical background it is evident that there has been a considerable development to that extent where in even high density materials can be easily conveyed. With many advantages over conventional conveying system, it stands in a...

Local Friction Forces between Plug and Pipe Wall in Dense Phase Pneumatic Conveying

Dense phase pneumatic conveying is widely used to transport granular materials or powder due to its efficiencies gained on cost and abrasion and erosion. To date these systems have been designed and analyzed using average frictional representation for the conveyed plug. This study explores the effect of this friction force by measuring strains on the pipe wall when the plug is moving passed the...
