COMPARISON BETWEEN THE KUTATELADZE–KHABAKHPASHEVA AND OSTWALD–DE WAELE RHEOLOGICAL MODELS IN DESCRIBING GENERALIZED NEWTONIAN LIQUIDS WITH THE USE OF EXPERIMENTAL MEASUREMENTS

The results of viscosimetric measurements of generalized Newtonian liquids (glycerin, 3% solution of Na–CMC, 70% water solution of starch, TNK Magnum SAE 5W40 motor oil) in the temperature range from 274 to 323 K and shear rates of up to 320 1/s are presented. The method of determining the rheological constants of the Kutateladze–Khabakhpasheva model and of the Ostwald–de Waele model of liquid viscosity power law for generalized Newtonian liquids is presented. The rheological constants of both models are obtained for the indicated liquids.
