WebAug 10, 2024 · The triangular ramp test was made popular for blood rheological testing by Bureau and coworkers in 1980 (Bureau et al. 1980). The hysteresis ramp is a relevant experiment for blood due to the unidirectionality of the shear waveform that is like the physiological flow in the arteries and veins.

When a more pseudoplastic fluid is tested, the shear rate in the gap tends to be the highest near the rotating member (the bob in the case of the Brookfield). This is because the shear stress is at a maximum at this point and the fluid tends to flow faster under high shear stress values.
