For the commonly used Bingham plastic model, the Hedstrom technique overestimates turbulent flow friction losses because it does not take account of viscous-layer thickening.
For laminar flow in circular pipes, the analysis of the flow of a Bingham plastic is a classical case that has been known for decades; but turbulent flow, and the transition between the two types, has been more resistant to analysis.
As noted above, the simple two-parameter model called the Bingham plastic is often employed to quantify this behaviour.
