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
