Polyacrylamide overestimates shear in oscillatory arterial models; leaves open validation of accurate blood analogs for hemodynamic research.
Polyacrylamide is too elastic to serve as a good analog for blood flow under oscillatory conditions, while Xanthan gum and glycerin are better but still imperfect models.
Mann et al. (1990) studied this question.
