摘要：

The paper describes the results of investigations of a swirling viscoplastic fluid fl ow in a cylindrical channel. It has been established that on increase in the limit shear stress and plastic viscosity, the effect of swirling on the flow structure becomes less expressed: the depth of the axial velocity dip decreases to its complete disappearance, with the hydrodynamic fl ow stabilization being observed over a smaller distance from the channel inlet. It is shown that at the same Rossby number the recirculation intensity increase with decreasing limit shear stress and plastic viscosity. © 2014, Springer Science+Business Media New York.
