On measuring wettability in infiltration processing

Capillary pressures encountered in composite processing are often evaluated by measuring infiltration rates as a function of applied pressure. Such data are generally interpreted assuming slug-flow. Using the Brooks-Corey correlations we relax this assumption, to indicate possible pitfalls of the slug-flow approach and to show how such data can nonetheless be used to derive meaningful capillary parameters.
