Mathematical Modeling of Swirling Herschel–Bulkley Pseudoplastic Fluid Flow in a Cylindrical Channel

Results of investigations into the swirling flow of a pseudoplastic fluid with a Herschel–Bulkley yield stress in a cylindrical channel have been presented. It has been established that a growth in the rates of shear strains in flows with a swirl causes the values of effective viscosity to decrease. It has been shown that at one and the same Rossby number, the recirculation strength is the greater the smaller the values of the limiting shear stress, the consistency, and the nonlinearity index.
