...Robert D. Stedtfeld; Glenn E. McCreery; Alan T. Stadler; Daphne L. Stoner; Paul Meakin A geotechnical centrifuge was used to investigate unsaturated multiphase fluid flow in synthetic fracture apertures under a variety of flow conditions. The geocentrifuge subjected the fluids to centrifugal forces...

...Laurent C. Levy; Patricia J. Culligan; John T. Germaine This paper describes an investigation into DNAPL behavior in saturated, smooth-walled, vertical fractures. A new theoretical model, which accounts for contact angle dependency on velocity and pinning of the DNAPL-water interface at the walls...
