| 摘 要： | 基于变尺度格子气方法，建立了气固相间曳力模型，对气固两相之间的耦合机制进行了研究，从微观角度出发，得到了气固两相之间相互作用的宏观行为。文章用此模型对气固两相流系统进行了模拟，模拟结果与四种经典曳力模型的模拟结果一致，验证了模型的正确性和有效性。

| Abstract: | A drag force model of gas-solid interaction base on variable-scale lattice gas automata model was established to study the gas-solid coupling mechanism from the micro perspective which obtaining the macro behavior of gas-solid two-phase interaction.In the paper,the gas-solid two-phase flow system was simulated with the model and the results agreed well with four classic drag force models,which verify the correctness and the effectiveness of this model. |
