| Summary: | In order to determine the nature of processes of the dynamic polymer flow with simple chemical reactions in two-dimensional cylindrical geometry, objects — a sugar melt and a high molecular weight fraction of glutenin of flour — were chosen in the hydrodynamic description, which were investigated on a rotational rheometer HAAKE RotoVisco 1 and the Moisture Analyzer OHAUS MB23. The nonlinear dynamics of a viscous flow of a compressible, homogeneous liquid with chemical reactions is considered. A nonstationary exact solution of the Poiseuille type is obtained. This solution is used to investigate the effect of viscosity and chemical reactions of the first order on the characteristics of the nonequilibrium dynamic states of the system. The present results of the joint research of the specialists of the All-Union Research Institute of the Confectionery Industry and the MEPhI are a continuation of the work on the formation of structures in food disperse systems and indicate that similar features can also be manifested in real flows of polymer liquids in various industrial installations. |
