The Pore Analysis GeoApps section contains a GeoApp for the calculation of the ASTM pore size calculation factor according to the ASTM E3278-21 standard. Also have a look at our GeoDict website.

The computation of the ASTM pore size calculation factor was tested and optimized on several metal wire weaves. In the ASTM test, the wire weaves are put in a containment filled with water, while air is injected from below the weave. The bubble point pressure is reached when the first air bubble pushes through the weave layer.

For the calculation, a precise analysis of the pore throats in the weaves is of major interest. Especially, the shape of the pore throat is a key parameter. Additionally, a correction factor for metal wire weaves is computed.

The available result files in the Data Visualization tab of the Result Viewer are the same as for the Bubble Point command.
