On the use of power equations to relate shear-rate to stress in non-Newtonian liquids

  • G. W. Scott Blair
Originals

Summary

It is shown that some quite simple assumptions about the nature of the flow of non-Newtonian liquids lead to the use of the well-known power relation between shear-rate and stress, hitherto regarded as entirely empirical. The treatment is applicable both to thinning and to thickening liquids provided there is no hysteresis.
