Nonlinear stability analysis of the full Brusselator reaction-diffusion model
Autor: I. V. Elyukhina
Publikováno v: Theoretical Foundations of Chemical Engineering. 48:806-812
We have constructed a general nonlinear parabolic equation for an autocatalytic reaction-diffusion model. This equation for the complex amplitude of the envelope wave allows one to analyze the long-term behavior of the system after a loss of stabilit

Analysis of long-time interaction of perturbations in problems of macrokinetics
Autor: L. P. Kholpanov, I. V. Elyukhina
Publikováno v: Theoretical Foundations of Chemical Engineering. 45:292-298
We developed an approach for the reduction of systems of nonlinear partial differential equations to the general nonlinear parabolic equation for a complex amplitude of an envelope wave. The equation is complexly derived: by using wave packages, meth

Johnson-Segalman fluid behavior in a oscillating-cup system
Autor: I. V. Elyukhina
Publikováno v: Russian Journal of Physical Chemistry. 80:819-822
Effects arising in a oscillating-cup viscometer when it is filled with fluids prone to nonaffine deformation were revealed. The efficiency of the method in identifying the rheological type and properties of such media in terms of the Johnson-Segalman

Identification of the nonlinear viscous properties of fluids by the vibrational method
Autor: G. P. Vyatkin, I. V. Elyukhina
Publikováno v: Journal of Engineering Physics and Thermophysics. 78:907-915
Effects occurring in an oscillatory viscosimeter upon its filling with nonlinear viscous fluids whose rheological properties are described by the Ostwald-Weyl model have been revealed. The possibilities of the vibrational method for identification of

Theoretical foundation of oscillating-cup viscometry for viscoplastic fluids
Autor: I. V. Elyukhina
The working equations of the oscillating-cup method for rheostable fluids are obtained. The method of description of viscoplastic fluid flows in unsteady viscometric systems without numerical formulations is developed. The solution features are noted

Analytical method for estimating the nonlinear properties of liquids by a torsion viscosimeter
Autor: G. P. Vyatkin, I. V. Elyukhina
This paper considers the motion of a torsion viscosimeter that permits a conclusion about the rheological type of the liquid filling it. We have developed a theory of identification of nonlinear properties based on the use of the effective values of
