In the above equation, σ 0 is the value of yield stress and η C is the value of Casson viscosity that is related to a high shear rate viscosity. Herschel-Bulkley model is another model used in yield ...
Many complex fluids, such as surfactant mesophases, network forming polymers, emulsions etc. do not flow until the applied stress crosses a certain critical value, called the yield stress. Materials ...
