Analysis of a nonlinear dynamic model of the Couette flow for structured liquid in a flat gap

Abstract

Parametric investigation of structured liquid Couette flow in a plain gap is presented. Bifurcation conditions of steady non-uniform solutions are defined from unsteady uniform ones in the nonmonotonic region of rheological curve. Relevant bifurcation diagrams are plotted. The coincidence between the steady-state solution and the solution of unstable problem is noted.
