TY - CONF AB - <p>Vertical wicking from an unlimited reservoir is investigated for electrospun ethylene vinyl alcohol membranes with varying fiber orientations. Neutron radiography is applied to create time-resolved maps of the moisture distribution during wicking. A transition at a critical capillary number from stable water front displacement to unsaturated capillary fingering is observed. While the wicking behavior appears to show little dependence on the fiber orientation during stable displacement, differences can be observed in terms of maximum height and finger shape during the later uptake phase with capillary fingering.</p> AU - Robert Fischer, P.
