Herschel-Bulkley Model

This Yield Stress Model incorporates the elements of a Newtonian , a Power law and a Bingham fluid:

with s_y the yield stress, k the consistency and n the power law index.

For s_y=0 and n=1 => Newtonian fluid

For s_y=0 and n#1 => Power Law fluid

For s_y#0 and n=1 =>Bingham fluid

Using This Model

This model describes many materials exhibiting a yield stress.

Can be used as a general-purpose model for many material systems.
