Description
Summary:The swirling flow of a thermoviscous, pseudoplastic Sisco fluid in a cylindrical channel was investigated. It was established that, in the case of irrotational flow of a pseudoplastic fluid in such a channel, the effective viscosity of the fluid in the neighborhood of the channel axis is substantially increased. A swirling of this flow leads to an increase in the rate of shear deformation of the fluid in the axial region of the flow and to a decrease in its effective viscosity. As the swirling of the flow in the channel increases, the fluid near the channel walls and the fluid at the boundary of the recirculation zone are subjected to a dissipative heating leading to a decrease in their effective viscosity. The intensity heating of the fluid in the channel increases with increase in the rate of swirling (the Rossby number) of its flow.
