A Comparative Analysis of the Ostwald–De Waele and Ellis Rheological Equations in Solving the Graetz–Nusselt Problem
The evaluation of the accuracy of the Ostwald–de Waele model in solving the Graetz–Nusselt problem is made by comparing with the standard solution for the Ellis liquid. As a result of the analysis, it is shown that the problem solution constructed on the exponential equation leads to substantial dis...

description | The evaluation of the accuracy of the Ostwald–de Waele model in solving the Graetz–Nusselt problem is made by comparing with the standard solution for the Ellis liquid. As a result of the analysis, it is shown that the problem solution constructed on the exponential equation leads to substantial distortions of the heat transfer pattern. |
