A multi-mode viscosity model and its applicability to non-Newtonian fluids

Abstract

There are many viscosity equations to describe a shear-thinning viscosity of non-Newtonian fluid. In the present study, a multi-mode viscosity equation to more accurately fit measured data was proposed. The viscosity data were obtained for aqueous solutions of carboxymethylcellulose using a cone-and-plate rheometer. Consequently, the fitted results using the proposed viscosity equation to the measured data were very good. © 2006 The Textile Machinery Society of Japan.
