Specific Surface Area Measurement by Air Permeability with Consideration for the Molecular Flow Effect [Translated]†

KONA Powder and Particle Journal, 2014
Because gas permeation through a powder bed is affected by molecular flow, applicability of the Kozeny-Carman equation, which neglects this effect, is limited to powders coarser than about 10 μm ...

Effective coefficient of diffusion and permeability of firn at Dome C and Lock In, Antarctica, and of various snow types – estimates over the 100–850 kg m⁻³ density range [PDF]

The Cryosphere, 2022
Modeling air transport through the entire firn column of polar ice sheets is needed to interpret climate archives. To this end, different regressions have been proposed in the past to estimate the effective coefficient of diffusion and permeability of ...
