✦ Synopsis

The permeability of two fine-pored carbons was experimentally determined as a function of the mean pressure, temperature, temperature gradient and gas properties. The gases used in the investigation were helium, nitrogen, argon and sulfur hexafluoride. A mean temperature increase was found to decrease permeability. The application of the Carman and Arnell model does not lead to a satisfactory prediction of the dependence of the flow on the gas properties. A new correlation for the experimentally determined permeabilities is presented. The experimental data of other investigators is also shown to be correlated by this technique.
