| 摘 要： | 利用格子Boltzmann方法对气固两相流进行数值模拟，其中颗粒的轨迹利用指数拉格朗日方法进行计算，而流场的计算方法则是基于一种修正后的LBGK模型．特点在于成功引入了两相耦合机制来处理模型中输运相和颗粒相之间的交互作用，这种新的模型适用于模拟气固两相流．

| Abstract: | This paper focused on the numerical simulation of gas solid two phases flow by lattice Boltzmann method. The particle tracks were calculated using a developed exponential Lagrangian scheme, and the approach used for the computation of fluid phase was based on a modified lattice BGK model. The study is characterized by employing two way coupling mechanisms to handle the interactions between the carrier phase and the dispersed phase in the model. This new model was applicable to simulating gas solid two phases flow. |
