| Abstract: | The experimental equipment of pneumatic conveying is introduced. The pressure drop prediction in horizontal plug-flow pneumatic conveying is reviewed. The calculations of pressure drop used three different method are earring out and are compared with experimental data. Numerical simulation using the methods of characteristics 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. |
