Improving the hydrodynamic devices for measuring rheological parameters of liquids.

Keywords: hydrodynamic rheometer, capillary tube, non-Newtonian fluid, plastic viscosity, yield shear stress, flow index, consistency index, measurement error


Variants of diagrams of hydrodynamic devices for measuring the rheological parameters of pseudoplastic and viscoplastic liquids operating in the constant flow mode and the constant pressure drop mode are proposed. Mathematical dependencies are presented for determining the rheological parameters of liquids, which can be implemented in industrial programmable controllers. It is shown that the proposed hydrodynamic devices make it possible to reduce significantly methodological errors of measurement of the rheological parameters of non-Newtonian liquids.
