Non-Newtonian Friction Loss Correlations
Specialized friction loss correlations that take into account the dependency of fluid viscosity on shear using non-Newtonian shear rate vs. shear stress relationships and empirical methods.
| Rheology Model | Correlation |
| Power Law | Darby 1992 |
| Bingham Plastic | Darby 1992 |
| Herschel-Bulkley | Chilton-Stainsby 1998 |
| Casson | Converted Power Law |
Correlations used to calculate head losses occurring between the flowing fluid and flow exposed conduit surfaces.
By Default, FluidFlow uses the the Darcy – Weisbach equation. However, these alternatives can also be applied in pipe components through the input editor:
- Shell – MIT
- Hazen – Williams
- Fixed Friction Factor (Darcy)
