“…CSA has been extensively applied since the pioneering works of Gale and Baskerville. [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Machine-made filter paper is not isotropic. That is, the flow across the grains encounters a greater resistance than that along the grain.…”
This work reviews pertinent literature in modeling by considering the water movement in filter paper to measure capillary suction time (CST). Both the diffusion-like and piston-like approaches are described. In addition, liquid saturation profiles in the filter paper for pure water and some slurries are experimentally constructed. Experimental results indicate that the unsaturated flow in filter paper is unexceptionable in all tests. However, the CST correlations derived from either piston-like or diffusion-like approaches resemble each other in form, which is attributed to the s profile near the wet front resembling a power-law-type behavior.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
