The importance of rheology characterization in predicting turbulent pipe flow of generalized Newtonian fluids

•Including high shear data in rheology characterisation is essential in obtaining good DNS results•High shear data also improves the accuracy of empirical correlations such as Wilson-Thomas•The exact form of the rheology models plays little role in the accuracy of DNS prediction.•Rheology should be...
