PLUG-FLOW DENSE PHASE PNEUMATIC CONVEYING

The experimental equipment of pneumatic conveying is introduced. The pressure drop prediction in horizontal plug-flowpneumatic conveying is reviewed. The calculations of pressure drop used three different method are carring out and are compared withexperimental data. Numerical simulation using the methods ofcharacteristics in a horizonal pipeline, the pressure drop in inclined pipeline, and the long distance plug-flow pneumatic conveying are reviewed. Finally, the development trends of this subject are discussed.
