Yielding viscosity for Herschel Bulkley model

September 21, 2004, 08:17

Hi,

I am attempting to simulate the laminar flow of a Herschel Bulkley fluid. One of the inputs required is the 'yielding viscosity' I am not sure what the value for this should be. I have checked the documentation but it is still unclear. I have values for n, k and Tau_0, which are commonly determined, however, I cannot find any information on 'yielding viscosity' Can anyone help?

Sincerely,

Godwin
