The Rate Of Fluid Absorption In Porous Media, Ran Wei Rioux

Electronic Theses and Dissertations

Fluid flow in porous media is an important process for many applications such as oil recovery, packed bed absorption colun~ns and filtration. Short time fluid uptake is important for processes such as textile sizing, paper coating and printing. But more work is needed to characterize the parameters that determine the absorption rate. This work is focused on short time absorption rate on uncoated and coated paper. Absorption rate is measured with a Bristow Wheel device for seven different uncoated papers and eleven coated papers. Gloss dynamics of freshly printed samples and tack dynamics are measured with two novel devices. Various …
