摘要:

摘要:根据量纲和谐定理,推导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。得到的关联式对空气重介质流化床床体关联因子计算具有很好的指导意义。

Abstract:

Abstract: The relevance between associated factors of moving particles is deduced based on the dimensional harmony theorem and a correlation applied to the air dense-medium fluidized bed is found. A series of experiments were conducted to study the relationships between swelling rate function and swelling rate; origin is used to simulate the relevance and draws the conclusion. Formulaic model matches the experimental results and the correlation coefficient of reaches 0.97. As a result, the correlation is very instructive and meaningful to the calculation of association factors in air dense-medium fluidized bed.

Key words: Keywords: pressure drop, swelling rate function, air dense-medium fluidized bed, correlation factors
