| Abstract: | The aim of this paper is to analyze the perturbed flows of a non-Newtonian incompressible second-order
fluid in a straight rigid axisymmetric tube with circular cross-section of constant radius. To study this problem,
we use the 1D nine-director Cosserat theory approach which reduces the exact three-dimensional equations to a
system depending only on time and on a single spatial variable. From this one-dimensional system we obtain the
relationship between mean pressure gradient and volume flow rate over a finite section of the tube. Attention is
focused on some numerical simulation of steady/unsteady flows on the analysis of perturbed flows. |
