On Application of the Ostwald–de Waele Model to Description of Non-Newtonian Fluid Flow in the Nip of Counter-Rotating Rolls

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

Zusammenfassung:The accuracy of the Ostwald–de Waele model in solving the problem of roll flow has been assessed by comparing with the "reference" solution for an Ellis fluid. 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 flow pattern.
