摘要
根据两相流的基本理论,建立了直管式气流干燥机干燥的数学模型。经验证,计算结果同试验数据吻合。本模型可用于一般工程设计,也可用于气流干燥机的性能分析。
A mathematical model for pneumatic drying using vertical pipes is devel- oped on the basic theory of two phase flow.The calculated results are well consis- tent with the experimental data.The model can be used not only for general engi- neering design,but also the performance anslysis of pneumatic dryers.
