| Abstract: | This paper presents a approximated analytical solution for measuring air permeability of unsaturated materials on the basis of falling-pressure method and obtains a approximated analytical solution for wet sample.Both analytical and numerical studies reveal that the agreement between the test data and the analytical prediction is satisfactory.Given a quantitative condition we can estimate the air permeability of wet sample using falling-pressure method with negligible estimation error. |
| Keywords: | Air permeability Falling-pressure method Analytical solution Air pressure Numerical method |
