ON APPLICATION OF THE OSTWALD–DE WAELE MODEL TO DESCRIPTION OF NON-NEWTONIAN FLUID FLOW IN THE NIP OF COUNTER-ROTATING ROLL

The accuracy of the Ostwald–de Waele model in solving the problem of roll fl ow has been assessed by comparing with the "reference" solution for an Ellis fl uid. As a result of the analysis, it has been shown that the model based on a power-law equation leads to substantial distortions of the fl ow pattern
