【 摘 要 】

A comparison of the results obtained from typical pressure drop models of fibrous media to experimental values has been done in the paper. Then, the pressure drop characteristics for different structural and operating parameters would be evaluated. The results show that Davies model instead of Kuwabara, Henry and Happel models fits well with the tested data and gives errors of less than 7.0%. Pressure drop across the media increases with increasing solid fraction, superficial velocity and fibre layer thickness, and decreases with increasing fibre diameter. Fibre diameter in the range of smaller values and solid fraction have more significant effects on the air flow resistance than the other factors.
