对气固多相流动的数值模拟的方法和描述气固多相流动特性的数学模型进行了分析。通过分析和对煤粉气流流过弯管时的流动情况进行数值计算发现：采用Ｋ－ε双方程模型描述气相湍流模型，应用ＳＩＭＰＬＥ算法计算气相速度场，然后采用ＦＳＲＴ模型，Ｌａｇｒａｎｇｅ 法计算颗粒场特性。这是比较行之有效的数值模拟管内气固多相流动的方法。图１３ 表２ 参８
The method of numerical simulation of gas-solid multiphase flow and the mathematical model describing gas-solid multiphase flow characteristics are analyzed. Through the numerical analysis of the flow of the pulverized coal flowing through the elbow, it is found that the gas-phase turbulence model is described by the K-ε two-equation model, the gas velocity field is calculated by the SIMPLE algorithm, and then the FSRT model and the Lagrange method are used to calculate the particle field characteristic. This is a more effective numerical simulation of gas-solid multi-phase flow tube method. Figure 13 Table 2 Reference 8
