| 摘 要： | 本文借鉴 Ｃｕｎｄａｌｌ＆ Ｓｔｒａｃｋ提出的碰撞模型，将欧拉方法和拉格朗日法结合起来，建立了喷动流化床气固两相流动的数学模型，在计算机上对试验台进行了模拟，探讨了床内颗粒的运动特征。按１：１的比例建立了喷动流化床的模型试验台并进行了试验，对模拟结果和试验结果进行了比较与分析。颗粒在喷动床内的运动特征，模拟结果都能够再现出来，模拟结果与试验结果取得了很好的一致性。

| Abstract: | The paper, which combines the Eular method with Lagrangian method and uses the Particle Collision Model put forward by Cundall & Strack, presents the model of the two- phase flow of the jet-spouted bed. The experiment study is made for the particle movement characteristic in the jet-spouted bed and the numerical simulation for the test-bed, which is constructed by the ratio of one to one, is also made in the computer. The comparison and the analysis are made between the simulated data and the experiment data in the paper. The particle movement characteristics in the jet-spouted can exhibited through the numerical simulation in the computer. The simulated results agree well with the experiment results. |
