摘　　要：阐述管道气－固两相流的紊流方程组，包括雷诺方程和κ－ε方程的双流体模型．讨论粉尘气流的密度、质量流率和粘性的计算．描述紊流模型参数的测量和研究紊流数学方程组的简化计算．最后给出管道除尘系统在环境治理工程中的应用实例．The gas particle turbulent flow equation of the air dust in the tube including two fluid model of the Reynolds and κ ε equation, and the computation of the particle density, mass flow and viscosity of the air dust are discussed. The simplified calculation of turbulent flow equation and the measure of the model parameters of turbulent flow are established. Finally,applications of the tube lay dust system in the environmental treatment engineering are given.
