Porter (b), Dorthe Wildenschild (a) Keywords: Capillary pressure; Interfacial curvature; Young-Laplace; Drainage; Imbibition; Computed microtomography Abstract: a* Computed tomography datasets were analyzed for interfacial curvature. a* Curvature and transducer-based measurements compare well. a* Disconnected and connected phase interfaces have significantly different curvatures. a* Connected phase interfacial curvature relaxes as the system equilibrates.
