摘　　要：根据量纲和谐定理,推导了床层压降与各相关联因子之间的关系,并整理得出适用于空气重介质流化床床层的压降关联式。在得出关联式后进行实验研究与数值模拟与的关联式;使用Mat Lab软件模拟两者之间的关系,得到膨胀率函数。模型公式与实验结果相吻合,其相关性系数可以达到0.97。Based on the dimensional harmony theorem, the relevance between different associated factors of moving particles was deduced, and a correlation applicable to the air dense -medium fluidized bed was found. A series of experiments were conducted to study the relationship between swelling rate and swelling rate function, MatLab was applied to simulate the relevance, and to obtain the function. The formulaic model matched the experimental results and the correlation coefficient reached 0.97.
