Abstract

The capillary breakup of thin free jets of dilute polymer solutions is investigated theoretically. The evolution of the jet surface shape in the nonlinear stage of deformation, when elastic effects are important, is described in the framework of a quasi-one-dimensional description. The initial tension of the jet is shown to have a decisive influence on the breakup dynamics. The delay in breakup due to the orientation and stretching of the polymer coiled macromolecules in the initial section of the jet is determined.
