Webcorrect for the flow field in the gap. 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. WebThixotropy of hand lotions - Stress ramps at 25 °C.
