Introduction of silicone hydrogel contact lens materials provided products of unprecedented capability to deliver oxygen to the eye during wear. One additional material characteristic of interest is the material’s permeability to ions. This paper discusses descriptive tools and optimization of an impedance method of characterizing ion permeability. A physical model of conductive paper with ...

The Effect of the Dispersion Term on Flux of a Fluid in Permeable Media

O. Toscanelli, and V. Colla
Scuola Superiore S. Anna
Pontedera, Italy

The flux of a fluid in permeable media can be modelled using a continuous. To link the real system with the continuous model is mandatory to realize a suitable average of the equations and of the variables. The dispersion term comes from this averaging but it is not only a mathematical product of the modelling. The dispersion is due to the intrinsic geometry of the permeable media that forces ...
