Non-identifiability in shear-thinning models warrants caution for hemodynamic flow predictions; leaves open the need for identifiable alternatives in research.
Parameter identifiability is an intrinsic problem in common shear-thinning rheological models used in hemodynamics, meaning inferred parameters cannot reliably predict physical fluid properties or flow behaviors.
Gallagher et al. (2018) studied Blood rheology. Shear-thinning rheological models was evaluated on Parameter identifiability. Fitting shear-thinning rheological models to experimental blood data reveals parameter non-identifiability, meaning parameters cannot be uniquely determined or physically interpreted.
