摘要
首先介绍了气力输送的实验设备.评述了水平栓流气力输送的压力降计算方法,用3种不同的方法计算了压力降并与实验数据进行比较.此外评述了用特征线方法进行水平管的数值模拟,倾斜管的压力降计算和长距离的栓流气力输送.最后展望了该领域的发展方向.
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.
