应用CFD软件Fluent对流化床内油页岩的流动特性进行了冷态流场模拟，并研究不同时刻、不同粒径以及不同弹性恢复系数对流化床内流化状态的影响。最终模拟结果表明：随着时间的推移流化现象越来越明显，同时颗粒粒径越小，弹性恢复系数越小更容易使气流稳定，有益于物料的正常流化。

Application of CFD software Fluent on the flow characteristic of fluidized bed furnace for cold flow field simulation. Study on the influence of different time,different particle diameter and different elastic recov-ery coefficient for the flow state in fluidized bed. . Final simulation results show that with time goes on the fluid-ized condition will happened more easily,and the smaller particle size,the smaller elastic recovery coefficient are more easily for flow stability,which is beneficial to achieve the fluidization process.
