DOI: 10.1016/j.ijheatmasstransfer.2018.10.054
Abstract: Abstract A simple technique for measuring the effective diffusivity, and ultimately tortuosity, in porous media is presented. The method uses a custom-built apparatus, based on a radial geometry, which eliminates the need for any gaskets… read more here.
