ABSTRACT

A simple and accurate procedure to determine the flow properties of powerlaw fluids using a paddle type mixer viscometer is described. The approach considers the mixer as analogous to a concentric cylinder system and incorporates the inclusion of end effects in modeling. The procedure significantly reduces data collection because calibration with standard fluids is not necessary to estimate average shear stress and shear rate values.
