摘要：
Zigzag-like forms of the capillary jet breakdown are detected. The zigzag-like structures observed develop when a water jet with polymeric additives flows out from a transverse oscillating capillary. The factor responsible for the unusual behavior of the jet is the elasticity of the polymeric liquid. An analysis of the jet shape made it possible to find the elastic stress distribution in the disintegrating jet and to establish the laws of rheological behavior of polymeric solutions in intensive jet flows. An algorithm for the numerical calculation of the zigzag-like jet profiles is proposed.
