Popis: | The tension of self-thinning filaments occurring upon the capillary breakup of liquid bridges in viscoelastic fluids is measured. The solution of high-molecular polymers with the concentration of 0.1 to 1% are studied. The stresses occurring in the filaments are determined and the effect of the hydrodynamic interaction between the filaments and the adjoining macroscopic volume (droplet) is evaluated. A theoretical analysis of the fluid inflow into the droplet shows that in the case of filament extension the rheology of the polymer liquids under consideration is different from that under the singleaxis compression in droplet flow. |
