Elastic deformations and anomalously high cutting ability of a polymer solution jet
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 85, Issue 1
Abstract
The article to determine peculiarities of macromolecule deformation behavior under conditions of a jet-shaping head that would allow to solve the issue related to the mechanism of increasing water-jet cutting power with polymer additions. There have been studied experimentally velocity fields and their gradients as well as the degree of macromolecule unrolling under pattern conditions of a jet-shaping head in PEO solutions flow. In converging polymer solution flow macromolecules are forced by a hydrodynamic field to rather strong (~ 60% and more) stretching that causes the field restructuring. The determined regularities of macromolecules behavior in the flow under conditions of a jet-shaping head and manifested in this case effects of elastic deformations have paramount importance in understanding the mechanism of «anomalously» high cutting power of water-polymer jet. Understanding the nature of increased cutting power of water-polymer jet will make it possible to develop recommendations on choosing regimes for water-polymer jet processing of food products by cutting.
