摘要：
Subject to the basic assumption of uniradial flow, a model has been established which allows the prediction of gas flow distribution in annular packed beds. Whilst of general application, the model has been used to simulate the flow distribution characteristics of a specific type of air filter incorporating an annular bed of activated carbon. All four possible flow arrangements have been investigated and it has been shown that U-type flow gives better flow distribution than Z-type flow.
