| 摘 要： | 运用基于颗粒运动分解思想的硬球模型模拟了气固两相流动系统的基本特征，讨论了操作条件对其的影响，其模拟结果表明：与国际上现有 用型模型相比，基于颗粒运动分解思想的硬球模型具有更为真实的优点，它能够定性而形象地复现气固流化系统的实验特征。

| Abstract: | In this paper, the basic characteristics of gas solid two phase flow are simulated by using the discrete model based on hard sphere theory. Moreover, the influences of operating condition on bubbling fluidization are also observed. The presented simulation results indicates that our discrete model can provide dynamic information of bubbling fluidization and shows the influence of operating conditions on bubble behaviors, which are consistent with experiment qualitatively. |
