Hi

I'm trying to understand how can i define shear stress parameters for Herschel-bulkley model in Comsol 4.2a
The stress expression for this model is:

stress = yield stress+m*(shear rate)^n


Any comments on this would be a lot of help.

Thanks!

Hello, did you succeed in achieving in what you wanted? I also want to model flow of viscoplastic fluid with HB-model.

Thanks and regards,
Yogesh

Do you get any answer on this to add Herschel-bulkley parameters?
