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.Abstract: 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.
