These fluids combine a yield stress with shear‐thinning behavior above the yield stress:

(3.25)

and

(3.26)

One may recognize that all three previous models are special cases of the Herschel–Bulkley model, making this the most versatile model commonly in use.

These four models are described visually in Figures 3.8 and 3.9
