In this paper, an experimental analysis has been carried out in order to characterize the rheological properties of non-Newtonian CMC fluids (carboxymethylcellulose CMC solutions). Two solutions at low and medium concentrations, respectively 0.5 and l.5%, have been tested. A comparative study of the three methods proposed by Mooney, Wiegreffe, and Geiger has been carried out. It was found that the two solutions follow the rheological power-law model of Ostwald/de Waele-type for the studied experimental range. The diameter of the flow channel influences the rheological behavior of the CMC solution and highlights the wall slip effects. For a 0.5% concentration, the methods of Mooney and Wiegreffe could not be used as they gave results that could not be explained physically. However, for a 1.5% concentration, the three of them gave satisfactory results.
