dc.description.abstract | Transient dynamics in viscoelastic fluids exhibits notable difference with their Newtonian counterpart. In this work we study the changes in the formation and decay of vortex of viscoelastic fluids due to degradation caused by shear stress. With this aim we performed long duration experiments with solutions of polyacrylamide confined between coaxial cylinders. The azimuthal velocity, acquired through digital particle velocimetry, shows oscillations before reaching a steady state. The vortex development is identified by the overshoot, which represents the difference between the maximum velocity and the stationary velocity. Similarly, during the vortex decay, the azimuthal velocity changes direction, and the relevant parameter is the undershoot, representing the maximum velocity of the transient reverse flow. The experimental results show that overshoot and undershoot are closely related to the changes in the viscoelastic properties caused by the mechanical degradation. This effect opens new perspectives in the characterization of the viscoelastic fluids. | es |
